Zac Efron took a trip down memory lane with Jimmy Kimmel on Thursday with a super cute home video.

While fans have been freaking out over the 10th anniversary of High School Musical, Kimmel took things way back with this vintage video of Efron's performance as Snoopy in a school production of You're a Good Man, Charlie Brown.

Like all home videos from a person's teenage years, it was all kinds of hilarious and embarrassing.
