Maybe He Thought It Was Crazy Pineapple
We just witnessed a player receive a one-round penalty for, well, trying to cheat. No shinola.
A player had left the table, and so there was an empty seat when the cards for the next hand were being dealt. A player sitting next to the absent player's seat managed to slide one (or perhaps both) of the absent player's cards closer to his hand, apparently in an effort to get a look and maybe find the best two with which to start.
The dealer saw what was happening and alerted the floor, and the penalty was subsequently delivered.
