Key holdem odds to memorize

I thought this might be a helpful thread for many players, myself included. I actually have a set of about 40 flashcards that I sometimes review on the bus when Im bored. Anyhow, I thought I'd tap the 2+2 talent pool to increase my flashcards. So here goes my first helpful odd to get the list going:

(By the way, does anybody know the odds of flopping two pair or trips holding two unpaired cards?)
