Seriously? OMG! WTF?

Before Jimmy Fallon hosted his own talk show, he was in the audience of Live with Regis and Kathie Lee (because he had a crush on her). How funny is the prank that the 21-year-old did in 1996 on the daytime talk show?

To hear Fallon tell Conan O’Brien the story, then

I love that Regis gave him shit over what he did?
