As some of you have said, sometimes you call them names that can't be printed here -- If I get disgusted because of a machine foul-up (even if it's my fault) I have this saying I use, "Everything in here starts with a "J" for "Junk" so if I have a foul-up with a machine, I'll cal it a piece of junk -- that's the only name I've called them!
