While he was on the show, the late night host shared that he had an old tape of Efron from his high school days — no not the musical — when he played Snoopy in a production of You’re A Good Man, Charlie Brown!
While Zac was obviously a bit embarrassed, he did a good job of distracting his fans before the show by taking to Twitter and sharing a shirtless pic of his BULGING biceps and pecs (above) with the caption:
“I woke up like this @jimmykimmel #dirtygrandpa “
Ch-ch-check out the AH-Mazing throwback footage of the 28-year-old and also see him show off his moonwalking skills!
