So, I’m not entirely sure this is really a mashup, but it is in my mind, so I’m going with it!
Mash-up of The Office and Harry Potter: Dwight Schrute as the Boy Who Lived! Yeah, that’s right. Dwight K. Schrute would be the Boy Who Lived, begrudgingly saving the world from Lord Voldemort. The jello with the stapler is actually a horcrux that Jim made (because he would be Lord Voldemort). I kind of feel like this is some weird fan-fiction going on.
Anyway, here is my picture mash-up!
The thing around his neck is a Gryffindor scarf. And the jello has a frowny face because it’s a horcrux.
