I once played these at a shower. They'd be best with a rowdy crowd
Hot dog in the jar game. . . Each guest has some sort of belt (their own belt, string around the waist, whatever works). Then you tie a hot dog with a string and attach it to the belt. So the hot dog is dangling between your legs. Teams do a relay race to be the first team to have everyone run down to a small mouthed jar (or large-mouthed if you want it to be easier) and insert the hot dog in the jar without using their hands.
Banana/condom game. . . guests are separated into teams of two. one team member holds the banana. The other member attempts to put a condom on the banana, again without using hands.
