Üter Zörker, voiced by
Russi Taylor, is an overweight
Germanforeign exchange student with a
sweet tooth, and odd habits such as offering his already-licked lollipops to others as a sign of friendship, and eating
marzipan candies (called
Joy Joy) fortified with
iodine. He was left behind on the
Civil War field trip, according to the season six episode "
The PTA Disbands", but was back in school, playing in the band in the season seven episode "
Lisa's Date with Density." His subsequent disappearance from the show for a significant period of time has become a running joke. In "
Guess Who's Coming to Criticize Dinner?" his biological parents from Germany asked Skinner where their missing son was, and in "
24 Minutes" he is seen stuck in a cobweb in the school air vents. It is revealed in the episode "
Jazzy and the Pussycats" that he can play the
trumpet quite well. He even makes a
Charlie and the Chocolate Factorydiorama, but eats it before it can be graded in "
Lisa's Rival". During the school science fair in the season 23 episode "
Replaceable You" Kearney has a human skull on display with a sign on it that reads, "Is This Üter?" In the German dub of the show, Üter is an exchange student from
Switzerland.
