Silliest excuse you have heard at an accident

Wheel Nut:
An old coach operator from the village took a bus load of pensioners out for the day, driving to the coast in heavy stop start traffic, he felt something, he stopped and got out, relit his pipe, sucked and said,

“how do you normally stop when I’m not here?”

sorry that one made me laugh im going to have to remember that if i ever get run into in the back
