Everything is more fun with balloons. They're colorful, they're exciting, they're sometimes filled with helium that will make your voice sound hilarious if inhaled. That last point is the most important in this clip. The great Alan Rickman was on The Tonight Show with Jimmy Fallon last night. Rickman had apparently taken offence to a game Jimmy Fallon played with previous guest Benedict Cumberbatch where the two took turns giving their best Alan Rickman impression. (It was a Rickman-off.) So he did what anyone would do, broke out The Tonight Show's truth machines (helium balloons) and had a heart-to-heart with Fallon. But it quickly turns into a hilarious showcase for high-pitched Professor Snape.
