best proposition bets

[snorer]

not sure if this is the right forum for it, but I couldn't think of a better one.

what are some good common prop bet scenarios?

I know the "drink-a-gallon-of-milk-in-an-hour" one is a really popular classic.

The other day I heard about a saltine eating one (6 in under a minute being near impossible), and eating a tablespoon of cinnamon. What else is there?

Mostly looking for ones dealing with things to eat, short physical tasks, etc, but looking forward to hearing all.
