Just thought of another:

Guys that tell me they're working out and running but "can't" seem to lose the spare tire around their belly. They say this to me while shoving a BK Double Whopper with cheese extra mayo and ketchup between their lips with "GO LARGE" chicken fries and a Coke.

I'm sitting across from them with a (homemade) grilled chicken salad w/ italian dressing, a big bottle of water, and an apple.
