Yo! Cartoon Network Raps
There was a time when Cartoon Network was a simple anime hub with a handful of old Hanna Barbera licenses it didn't know how to capitalize on. Thankfully the channel has crazy people at the wheel, is not afraid to experiment, and now yields things like this and this.
Also, they always have amazing ads like the one below. It combines all of my favorite things: cartoons, motion design and kids rapping. CN, you complete this.
