Don't I Know You? is a challenge where the jokers had to tell a stranger that they know them, tell them how they know them by the other guys' embarrassing cue cards, and if the stranger doesn't admit they know them, the Joker loses. It appeared on the episodes called Boardwalk of Shame, Starfart Macchiato, and Theater del Absurdo. In Season Two, there was a version where the strangers guess what celebrity they look like and another version about whether someone has seen their wife.
