There was a guy who was watching someone's kid and when the Dad gets back, they are playing cards at the table.
The kid proclaims, "I win!" and he has a handful of worthless cards (playing poker) but the adult isn't able to explain the game so he let's the kid take all of the chips. THe kid says twice, "I win... " and then, "Because I win!"
Does anyone recognize the premise of this scene?
