$5 birthday card transforms into instant shot glass

This is the card you want to send to all your party-loving friends: Made by Fifty Five Hi's, it proudly boasts that the "First Shot's On Me!" -- then delivers on that promise in a pretty incredible way. The card is cleverly constructed to hang from the neck of a bottle, and as long as your pal's patient enough to master some basic origami, they can fold an attachment to the card into a pretty cool shot glass. The tiny cup is strong enough to actually drink from and "holds approximately 1oz of liquid without leaks for hours." Not that we're advocating anyone drink for hours, of course -- enjoy your birthday in moderation!
