AA...sometimes.

For example, tonight I'm running card dead - there are 11 players left-bubble time- and I'm in the BB with AA.

I raise 4 times the BB, about 1/3 of my chips - a player calls. Flop is K,7,2 and I'm feeling like king of the table and go all-in, damn the consequences...until the other player turns over 77 and my head turns into a giant sucker...

So yeah, AA donks me sometimes.
