I've heard of a D'n'D campaign where that was done, sort of... It combined panty raid with scavenger hunt. The goal being to get one or more panties from one of each of a list of species; Dwarf, elf, human, taurian, tiefling, dragon-born etc.

The kicker was the last one was a succubus, who usually don't wear panties!

I suspect a large amount of alcohol was consumed in the creation of that idea.
