Nice find Tony-Z, I have not seen that one before. I'm going to hot-link it over to a discussion in another forum if you don't mind (see below).
EDIT: replaced truck images with different ones.

What show is that from? I just picked the image off the Internet today, it is funny.
EDIT: was talking about the form, but the truck thing is better.
