Actor Daniel Radcliffe is known for concocting spells and fighting off demons in the Harry Potter series, but hidden behind the mythical cover is a man who loves a good tongue-twisting rap song. Radcliffe—who's on a press run for his upcoming movie Horns—chopped it up with late night host Jimmy Fallon on The Tonight Show to discuss his love for music and how he's managed to memorize some of the most rapid paced lyrics in the game.

Watch Daniel Radcliffe perform a personal rendition of Blackalicious' "Alphabet Aerobics" while Fallon watches behind him in amazement as he passes through the letters of the alphabet.
