Or the hypocritical version: "Sorry, I just farted. I'm too ashamed."

I usually stare at someone else in fake disgusted and pretend they were the ones who farted.

We should start a spin-off thread or two: one for the excuses towards the others in the elevator: "Sorry, but I have a wiccaphobia." and one as an excuse to the old lady: "Yes of course, ma'am, I'll test the elevator for you!"

We were discussing the Self/less movie yesterday, and it occurred to me that it was about:

Gandhi (Ben Kingsley) taking possession of Deadpool's (Ryan Reynolds) body.

I am thinking Deadpool's girlfriend would be disappointed.

Don't know how you will submit play-doh (play d'oh! for Homer ) in exam, kind of messy for prof. to reconstruct proof.

I wasn't planning on it, but I was wondering if they would let me bring it in anyway as a sort of...topological calculator.

They will let you bring it, but will they return it, too?

I remember the line, a classic one IMO by Rodney's character, upon seeing Sam Kinnison ( Prof. Terguson) shouting, in response to , basically, every thing:
" I like this professor, he really cares. About what, I have no idea ".

EDIT:
The actual line was : " Good teacher, he really cares. About what, I have no idea "

Reminds me of when I was 16, and I was trying to discuss the "gas pedal", and inadvertently called it the "starter pedal".

It took me years to reconcile why I called it that.
1. There are a lot of doohickeys in a car, with a myriad of names, and I'm probably going to get some wrong, without some practice.
2. My "starter pedal" made the car "start" moving when you pressed on it.

ps. I believe in the olden days, that device was sometimes also called the "accelerator pedal".

pps. Actually, I'm going to blame my confusion on the auto industry...
5 year old Om; "Daddy, what does that button on the floor do?"
Daddy; "It starts the car."

Brother; "Why are you pushing on the high/low beam button?"
16 year old Om; "Dad told me that button starts the car."

25 year old Om; "Where did all the buttons on the floor go?"
Car; "They're now up here on sticks, and incorporated into the ignition switch."

58 year old Om; "What? Toyota now has an automatic high/low beam light thingy? What happened to all the buttons, switches, and other stuff?"
The future; "Technology".
Om; "Oh. Ok. I'm cool with that. Just don't expect me to remember the names of anything..."

This guy I know here (age 25) has a '65 Beetle and he keeps calling the points "dots." I suspect this comes from geometry class where a "dot" is made on paper to represent a Euclidian "point." Regardless, it's very confusing to hear him talk about "adjusting the dots."

I think what he is discussing, is an expansion of what we called; "connecting the dots", back in the olden days.
Oddly enough, this makes total sense to me.

You lost me at "points."

How does one adjust points as in this VW case?. EDIT2: The whole " connecting the dots" thing sounds very " Tubular" , i.e., very So Cal.

There used to be a time when you couldn't walk down the street without stumbling over a guy who could explain how to adjust the points on a car and check them with a dwell meter. So many people used to fix their own cars.

OCR's link shows a set of disembodied points removed from the distributor. Adjusting them is a matter of installing them in the distributor such that the cam follower bears on the cam the right amount so that the contacts are closed and opened through approximately equal amounts of cam rotation. A 4 cylinder car, like the Beetle, has four lobes on the cam. That's four 90 degree segments. Ideally, you want the contacts solidly closed for 45 degrees, and then open for the remaining 45. The number of degrees of rotation during which they remain closed is called the "dwell." The wonderful "dwell meter" will tell you exactly what your dwell is while the engine is running. If it is out of spec, then you have to stop the engine and physically push the points toward or away from the cam with a screwdriver. That is a very irritating, fiddly job because a small amount makes a big difference. I have heard tales of more enlightened distributors that make it very easy to adjust the points by the inclusion of an adjusting screw, but the Beetle does not have that.

Two or three companies make an aftermarket electronic distributor that does away with the points. That's what this guy I mentioned put on his Beetle because he didn't want to mess around with "adjusting the dots."

GM's were that way. Access through a little door on side of the cap that slides up.

But on V8's their distributor was on the rear of the engine and difficult to reach.

It was.. I am studying for my topology qualifier!

31 days!

Really 30 days and then the 31st day is the day of the test.
I've upped my studying from two hours a day to four.. 4-6 am (before work) 7-9 PM after work, homebabywife. It's a strain on her too because the baby is exhausting. I'll try to entertain him from 5-7 somehow.

I better pass this damn thing on the first attempt.

I once spoke with a GM engineer about the cars a plant that he worked at. He told me that in order to remove the spark plugs on some models of the car, required disconnecting the motor mounts and lifting the engine several inches. Definitely not your average backyard mechanic capability.

GM had some issues in the 70's that i remember. When a new line of engines didn't pan out they had to shoehorn in an older bigger one. But those cars were fast so appealed to motorheads.

As emission stuff engulfs engine compartments it's just awful working on cars now.
On the other hand, spark plugs now last 150,000 miles . And the computerized fuel injection makes today's engines right out of the factory better "Hot Rodded" than we average guys could make them ourselves in the 60's.
My little fifteen year old Ford Escort with its four tiny cylinders has highway passing performance every bit as good as my 1960's V8's with 3X the cubic inches.
And does it on half the gasoline. Just got back from a 1025 mile trip on 31 gallons of gasoline = 33 mpg . Newer ones do even better I'm told.

In the four years I've owned the little car it's completely repaid the purchase price in gasoline i didn't have to buy for my V8 Oldsmobile .

Were it a Japanese make I'd name it "Madame Butterfly" because it has been faithful yet will one day be abandoned , left at the salvage yard. That'll be a sad day for me - i'll feel like Pinkerton..

It was the 1980 Chevy Citation X-11.
From the https://www.edmunds.com/car-reviews/features/100-worst-cars-of-all-time.html:

52. 1980 Chevrolet Citation: Chevrolet's first front-drive machine proves to be legendarily unreliable and one of the most recalled cars of all time. Yes, the Pontiac, Buick and Oldsmobile X-Cars were just as awful.

The engineer told me at the time that the Citation set a record for major and minor recalls. Most of the cars were a side mounted inline 4 cylinder FWD. The problem was the X-11 version was a V-6 that they stuffed into the same space so you couldn't get to the plugs on the firewall side.

Beetle geezers at the Beetle forum think I'm a moron. I'm not, but it can look that way to someone who has been fixing Beetles since they were first introduced to the states. Some of these guys, if you completely dismantled a Beetle, including the engine, they could put it back together without consulting a manual.

You mean the company that recently doctored safety records is doing something stupid?

To be fair, old Beetles were engineered by completely different crop of people and there was never any attempt to deceive anyone about anything with the old air-cooled VW's. They were very inexpensive because they achieved everything in the simplest possible way, which often meant the crudest way. Some Beetlers refer to them as glorified lawnmowers or glorified go-carts, but they are really, I think, enclosed 4-wheel, 4 cylinder motorcycles. In any event, once you get to know one, it's hard to think of them as real cars.

Wonder if it would make more sense for trash pickups to be alternated weekly so that all homes or businesses in a given block put the trash in the same spot, while rotating the spot weekly . I mean, say we have 6 places in total, p1,p2,...,p6 in one block putting out trash. Then the first week everyone leaves their trash in front of p1, following week they do so on p2,.., etc (and back to p1 after 6th week). Then the garbage truck needs to do just one stop. A small, workable problem may be for those picking up the trash to know where, what block, the trash has been left in a given week.
