In the “why the hell did it take them this long” category: shot glass size red party cups. It’s an idea so obvious everyone missed it.
Sure, you can take shots out of normal size red party cups. You can also take shots out of a garbage can. But neither is as civilized as having some of these novelty little cups on hand.
Plus they are perfect for teaching hamsters how to play beer bong. Hamster beer pong! (Hamster size ping pong balls sold separately.)
You can order these miniature party miracles over at ThinkGeek.
