Gone In An Hour drink recipe

Fill a glass half way with cola, then place a cotton shirt over the cup (no joke). Poke the shirt so that it just touches the coke using a finger, and gently pour the shot of vodka through the shirt. You should have a layer of coke, with a layer of vodka on top. Down it all at once and all you'll taste is the coke. Careful though. You won't realize how much you've had until it's too late.
