Kevin Smith In 'Grease': 'Tonight Show' Finds Footage Of Director Playing Kenickie In High School Play (VIDEO)

Kevin Smith got to revisit his teenage years on "The Tonight Show" (Weeknights, 11:35 p.m. ET on NBC) Wednesday.

Jay Leno rolled footage from a high school production of "Grease" in which Smith played a rather static-looking Kenickie.

The "Babble-On Begins" creator then jumped up to show Leno his signature Kenickie hip swivel, which hadn't gone down too well with his mom at the time.

"My mother’s like, 'Never do that again,'" he laughed. "And I said, 'Because it’s dirty?' And she says, 'No, 'cuz you look pregnant.'"

"The Tonight Show" airs weeknights at 11:35 p.m. ET on NBC.
