haha. i did something similar in a home game once.

i make a habit of looking at my cards once and only once per hand, and im very good at remembering exactly what they are, even after 93 whiskey and cokes. well one night my memory was off-by-one and i remembered AND BET my cards from the previous hand on the current hand. needless to say at the showdown my A8s or whatever was nowhere near A8s.
