I mean, why not a romance d20 minigame? Hit points become heart points...get to -10, and you shall truly never love again.
[Hijinx is fine...it's not really about pretending to be a band, it's about pretending to be a tongue-in-cheek homage to an extremely stylized version of rock bands seen only on cartoons.]
Ponder this...what about those Swordfighter's Guild/SCA guys? They're outside, they're exercising...they're hitting each other with PVC pipe swords. We're discussing turning a sport into an RPG...these guys have turned D&D into a sport.
