I used to work at Geek Squad, and pranks are sorta ingrained into the culture. As a bit of background, our job title was “CIA”, for Counter Intelligence Agent (as in, the “front counter” of the store). Definitely ran by nerds.

Anyway, when you get your CIA badge (literal medal badge, dubbed a “shield”), there’s typically a ceremony, it gets presented, it’s like a badge of honor, no pun intended. So when someone got theirs, I put it in orange jello. This guy had regularly yoinked other people’s badges and would take random photos with them, it was good fun and harmless.
