Zac Efron took an embarrassing trip down memory lane on "Jimmy Kimmel Live!" on Thursday night.
The late-night host surprised his guest by sharing footage of the "Dirty Grandpa" star playing Snoopy in his high school's production of "You're a Good Man, Charlie Brown."
It seems Kimmel got the video from Zac's high school drama teacher, Robyn Metchik.
"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," Jimmy teased. "Oh, no!" Efron replied. "Are you serious?"

In the video, he belted out the tune "Suppertime" and even moonwalked across the stage with ease!
Even though the "High School Musical" alum should have been proud of his performance, he couldn't help but cringe as he watched.
"Nice moonwalking! Very impressive, by the way," Kimmel said. "Back then, that crushed. That was like a big deal," Efron quipped.
"That would crush right now if you did it, by the way," Jimmy declared.
And just like that, the actor got up and proved that he can still groove like he did in high school. Check out the clip to see him in action!
