By now, you're probably familiar with Magnitude, the character from Community whose "pop pop" catchphrase is sweeping the nation. But chances are you didn't know that Magnitude, a.k.a. Luke Youngblood, is a British actor who also appeared as Lee Jordan in two of the Harry Potter films: Sorcerer's Stone and Chamber of Secrets.

Having both Hogwarts and Greendale on your resume is quite impressive.

At last week's Comic-Con, Community star Donald Glover discussed how the "pop pop" catch phrase is a fan favorite despite the fact that it was originally meant as a one-off joke.

"It's nonsense," Glover said. "The joke of it is that it's so shitty."

Glover went on to say that hearing Youngblood deliver his "pop pop" lines is even funnier considering he speaks with a proper British accent.

"Luke Youngblood: You couldn't get more British if you wanted."
