Happy BYO Cup Day! For the uninitiated: BYO Cup day is 7/11's annual celebration of the Slurpee where customers are invited to bring their own cups along and fill them to the brim with Slurpee.
Grab a cup (and make sure it complies with the rules) and get down to your local 7/11 for some Slurpee-goodness.
If you hit up BYO Cup day, send us your photos! What's the weirdest thing you saw getting filled?
HERO UPDATE: Mark sent us his effort. Watering can Slurpee!
