It’s always a blast when A-list celebs appear on The Ellen DeGeneres Show, but what happens when another comedian stops by? Hilarity ensues. That’s exactly what occurred on Friday when Jimmy Fallon dropped by the funnylady’s talk show, where the 57-year-old TV personality kicked off their chat by scaring the heck out of the Tonight Show host. During the interview, the conversation turned to the topic of Fallon’s very first Tonight Show, and he admitted his parents certainly didn’t help to quell his nerves. Fallon said, “I came out and did some jokes, and I made a joke about high school or something. Of course, my mom and dad are in the audience because it’s my first Tonight Show—and my dad heckled me. Can you believe that?!”
