The Dynamic Duo... in color! by @Biscuits (Elli Gibbs)
The Chronically Unhappy siblings freed! Freed to bring mayhem and chaos to their former oppressors. Actually, they probably just want some muscle relaxant for their faces; grinning like that probably hurts like hell.
Hey! Haven't you ever heard it takes more muscles to frown than to smile?! Good job on the pic BTW, i really like the backround too.
