52 pickup

52 pickup or 52-card pickup is a card game which consists entirely of picking up a scattered deck of playing cards. It is typically played as a practical joke, where the "dealer" invites unfamiliar players to play a game of "52 pickup" (implying it is a legitimate card game), only to throw all the cards into the air so they land strewn on the floor, and instructs other players to pick them up. The Encyclopedia of American Folklore (1960) describes it as a "popular American prank", noting that it works best on younger children who are eager to be involved in play and less likely to ask questions prior to the game. The game is also popular in Germany as 32 heb auf.
