Jib-Jab

Jib-Jab has taken a hallmark of lazy internet animation (the cardboard cut-out motif), and refined it. From the subtleties of it's animation to the quality of it's music and celebrity impersonations, their shorts are 3 minute masterpieces.

Recently they've launched a service that allows you to place you and your friends faces into one of their pre-made skits. Hilarity ensues.
