list your most moronic thing you've seen done to a car

I was out in the shop today and it made me think to post this question. I bought a 69 dart from a buddy of mine for parts. when I got it home I realized that at some time somebody put 71 a body bucket seats in it. Well, rather than drilling holes in the floorboards they took a cutting torch and blew right through the original seat track bolts and into the floor. So today I'm in my shop restoring the 71 bucket seat tracks. List the most moronic thing you've seen done to a car
