Seriously, that hair. Total perfection!

Even though he looked like a million bucks in high school, the 53-year-old actor has admitted that he wasn't a cool kid while growing up in Orange County, California, high school.

Click through to see photos of the actor:

"I know everybody says this, but in high school, I really was the dorky kid," he told Orange Coast magazine in 2014. "I was into magic and theme parks. I was very innocent. When a lot of kids my age were going out drinking on Friday and Saturday nights, I was at Disneyland, going on the rides and listening to the bands."

How times have changed!

Stamos went on to star as ultra cool Uncle Jesse on Full House in 1987, a role he will be reprising in the upcoming Netflix series, Fuller House.

That, of course, happened after his acting debut on General Hospital and a touring gig with The Beach Boys.

While performing as an honorary member of the classic surf-pop band in 2014, Stamos made one Beach Boys fan's dream come true -- watch in the video above.
