Jimmy Kimmel: Justin Bieber Fans Say He Can Punch Grandma, Pee On Flag, Drive On Baby Seals (VIDEO)

Jimmy Kimmel wanted to see how blindly Justin Bieber's "obsessive" beliebers would follow him, so the talk-show host sent his Lie Witness News crew to the Staples Center in L.A. to find out. The answer, of course, is "very, very blindly."

Kimmel asked his fans about made-up facts like Bieber's car tires being made of baby seals, that he tours so much he doesn't have time to learn to read, that he peed on the American flag and, best of all, the he punched his grandma in the stomach. I'd tell you the responses, but you really just have to see them to belieb them.

Oh, and in case you were wondering how the concert was, Kimmel gave us a rundown on that, too: "It went 'baby, baby, baby, girlfriend, girlfriend girlfriend,' and then he went home."
