WOOPS. Forgot the final Shark Week sketch! Day 7 (final): DerpShark.
The Derpshark is the stupidest creature known to man, often starving itself out of sheer laziness or simply annoying larger creatures to the point of killing the defenseless Derpsharks. They are most notable for their distinctive "Durr" call, as they roam sandy seashores in search of mates and food.
