Reddit, I'm a mechanic, I broke rule No.1. What stupid things have you done that your profession dishonors?

Well, it's not a big deal but rather a dumb thing that happened to me that should not have happened...

So today I was cleaning some parts with gasoline and my hands were black from the oil and gas, and I really had to pee.

So I went for it and did the one thing I should never do, grab my ENORMOUS 6 inch wang with dirty ass hands.

Needless to say, scrubbing your scrotum to make an oil stain come out is not fun (and painful at that).

What is something that you should never do with your profession but you still did anyway, and walked away rather unharmed? And/or without getting fired/reprimanded/etc.
