Zipper University is a university in Daten City. This university seems to be solely for zipper-like creatures. Chuck and Fastener both attended Zipper University, and fell in love with the same cheerleader, whom Fastener later had sex with.
Zipper University has a lot of similarities with Daten City High, for example: both have a losers' class (where Chuck was put in), a queen bee and cheerleaders. Zipper University was first featured in "Chuck to the Future".
