Alan Rickman struck fear into the hearts of Hogwarts students as Professor Snape, but the Harry Potter star didn't sound too menacing on The Tonight Show earlier this week.

When Rickman sat down opposite Jimmy Fallon, the actor wasted no time before confronting the host about his 2013 "Rickman-Off" with Benedict Cumberbatch. Armed with "truth-telling" helium balloons, Rickman coerced Fallon into a squeaky-voiced apology, but Fallon had his own plan in mind. The SNL alum eventually coaxed the actor into saying "Harry Potter" after taking a few puffs from the helium balloon himself, changing the way you'll see Snape forever.

Hot, hot, hot TV eye candy!
