Gay driving past a mental hospital when the wheel falls off his car ,standing at the side of it wondering what he's going to do when he spots a man looking over the wall from the hospital,the inmate says to the bloke why don't you take a nut of each wheel so you'll have 3 nuts on all 4 wheels and that should get you home that's a great idea so the bloke does as the inmate says and before he drives off says that was a great fix what are you doing in there and the inmate says in in here because I'm mad not f***ing stupid =)
