Watch Will Arnett and Jimmy Fallon Karate Kick Pinatas

YouTube/Screengrab
Will Arnett may be in Teenage Mutant Ninja Turtles — but that doesn't make him a ninja. At least, that's what Jimmy Fallon must have been hoping when he challenged the actor to a game of Karate Pinata (yep, that's a thing).
The blindfolded stars had to kick pinatas into smithereens, and the results were pretty funny.
This is definitely not in a book.
Jimmy Kimmel had a pretty great bit with Reading Rainbow's LeVar Burton — whose Tweeting Rainbow showed sort of a modern take on the public TV classic.
Basically instead of learning how to read, these kids learned about favorites and retweets. Plus, he showed a pretty awesome picture of a cat wearing a Geordi La Forge visor (exactly what Twitter was invented for).
