Trading Places? (vague spoiler)

Derp! I didn't see your post, and put one up top myself regarding this. Will remove mine and repost here!

Dark homage to ..."Trading Places"?

I didn't think that at all along the way, but at the end, when Craig was wandering off with his winnings, and Koechner's character gave his wife what appeared to be a 20(?), upon losing his bet as to who would kill who, it had the same feel to me as the reveal of the bet between the older guys in "Trading Places".

A small sum of money bet upon something that resulted in an expense of a good deal of pain for others... anyone else feel this?

Yep, when he handed over that small bill and was disappointed that his wife won the bet, I yelled out, "Trading Places!!" Awesome that others noticed that as well.
