I'll start with the animated stuff.
Adventure Time, Regular Show, Phineas and Ferb, Kick Buttowski, My Little Pony: Friendship is Magic, Futurama, Ugly Americans, South Park, American Dad, The Avengers: Earth's Mightest Heroes, Archer and Jimmy Twoshoes.
The live action stuff.
Dexter, Weeds, True Blood, Hung, Spartacus: Blood and Sand, and a bit of It's Always Sunny in Philadelphia.
Pixel Art can be fun.
