I was still rather green, dealing 30/60 (our highest game, full of obnoxious snooty types), and I spread four cards on the flop. Twice. After that I got a new setup and learned to deal out the flop cards differently.

At my regular drunken crazy donkfest Monday nights, I once dealt out a flop using the other deck. Nobody noticed except for me after it was over. I elected to move on without saying anything (two players, short-stack all-in preflop, best hand won unimproved).
