Yep, those are the ones that really piss me off. I find them intellectually insulting.

On a side note, I've never been one good at being on time for work, though when I show up I'll be there as long as is required. Anyway, one job I had when I'd finally drag in 15 minutes to an hour late my foreman would come up and say "Ok, so why were you late today Kim?"

I'd always ask him if he wanted the truth or a good one? Some days he wanted the truth and got it. Other days when he wanted a bit of humor he'd ask for a good one and always got that too .... which usually involved aliens, car jackings, tales of drunken adventures the night before or a good hot babe tale
