The Jerk Basket is a giant version of Spencer's favorite boardwalk game that he rigged up for the Halfoween party during the episode iHalfoween. The player is attached to a harness and lowered into a basket of fabulous prizes at which point he/ she has 8 seconds to grab as many prizes as they can before they are jerked back up out of the basket.

The game becomes a tool of revenge when it is used on Freddie (mistakenly) and then Nevel in punishment for his prank on Carly, Sam and Freddie during the party.
