Other than the obvious one can use condoms for many things: as boxing gloves, as a banana protector, for bondage on a budget, as saran wrap for butter, to hit someone in their balls, as a garrote, as an elastic, as a slingshot, as a speed bag, as a piñata, as a doo-rag, as fake breasts, as waterproof socks, as friendship bracelets, as hair ties, as an iPod protector, as spoon-chuks, sink-sized water-filled projectiles - up to tub-sized, as a halo.
