Had it not been for Robyn Metchik, Jimmy Kimmel Live! wouldn't have received archived footage of the Dirty Grandpa star performing in his high school's production of You're a Good Man, Charlie Brown. Unlike some child actors, Efron attended a "legit" public school. Jimmy Kimmel surprised his guest with the video Thursday, saying, "It might be fun for us to talk a walk down—well, really, just memory lane for you—and a brand new undiscovered lane for us."
The 28-year-old movie star cringed as the video showed him singing "Suppertime" in character as Snoopy. "Nice moonwalking!" the late-night host told Efron. "Very impressive, by the way."
