What stupid things have you done?

Before I contine on with my idiot move of the day, I'm curious of what others may have done that wasn't exactly a smooth move, and you may not want to admit.

To get started, I'll start with one.

When I first got my Duster, the interior was pretty nice (other then the carpet). Not ONE tear in the dash. It was pretty amazing really. Then I decided to install new carpeting. When I took out the bench seat I kind of had to twist it a certain way to get it out. I finally got it loose, and when it came lose I heard it hit something. Since It was loose though I just decided to continue to pull out the seat. After the seat was out. I notice the stud of the seat went right into the dash and tore all the way out the door.

Real nice huh? The dash made it 35 years, until I got to it! :banghead:

That sucks.
My dealership experience kept me from ever doing that one, but I've had my share of screw ups like the time when I had a lower oil pan off of a mercedes to replace the oil level sensor.

Before adding the tube type sealant to seal the lower portion of the pan, a trick to keep the oil from running onto the mating surface was to stuff a red rag at the rear of the pan to catch residual.
Well, some rocket scientist at the shop wanted to save money and did away with the red rags and got a crappy company with used, worn out, formerly blue rags that were now faded gray and really blended in with the aluminum oil pans....can you see where this is going???

Well I got it all sealed up and took it for my test drive after the lunch break gave it time to set up, and the car ran fine under load but was ticking real bad at idle.
I knew exactly what happened and when it hitme I felt like I swallowed my own stomach....you know that feeling.

Well, I got it back to my lift and pulled the drain plug and found my rag, it was coming out in clumps.

I had to tear the motor apart , clean it and replaced all the rings and bearings to play it safe.

I thought I would get fired for sure but the service manager liked me and actually chewed out one of the shop foreman for getting rid of the red rags because he knew they would blend in and be hard to spot under the hood or in and engine which is the reason we had red rags in the first place.
I felt like a total moron especially when it was brought up at the next Monay morning meeting...ugh.

I don;t feel that bad because their was a tech that left a rag in the engine compartment of a brand new pre delivery inspection car which happened to be an SL-55 AMG and the customer was there to pick it up.
During the test drive the tech noticed a smell, then smoke, hten opened the hood to find the engine compartment on fire.
The rag was on the catalyst and the car burned to the ground right there.
