John Stamos, 56, Shares Shocking Senior Throwback Photo On Instagram

John Stamos, 56, shared a shocking senior throwback photo to honor the class of 2020, many of whom have been disappointed by not being able to participate in a formal graduation ceremony with their peers. The Fuller House star posted the pic and some words of encouragement for students, sharing his own high school story in his caption.

John's picture, taken 39 years ago in 1981, shows the future actor in a graduation photo from his alma mater, John F. Kennedy High School in La Palma, California. He wore a tan suit jacket and a wide-lapel brown shirt.

In a style reminiscent of the era, John's hair was long and feathered, blown away from his handsome face. It was also an orange hue. John alluded to the color in the caption, stating that the use of a popular highlighting product of the era "seeped into my brain." He sported a golden tan in the photo and his eyes were happy and bright.

The actor asked his followers to share their graduation photos with him and to tag him in the caption of the pics, noting he would share them on social media. He also asked his celebrity pals to participate in the challenge as well.

Fans loved the photo and commented on the throwback look and the actor's challenge as well.

"You went to high school with my mom! She has this picture in her yearbook!" exclaimed one fan of the actor, who shot to fame right out of high school in the soap opera General Hospital, where he played the character of Blackie Parrish.

"Is it just me or does John Stamos look like Zac Efron there?" queried a second fan, who found some facial similarities between the High School Musical star and the Fuller House actor.

"OMG...Sun-In! I remember really messing up my hair with that once at my Grandma's. Spending all day in the pool in the Summer. My hair was Urangatan," said a third follower who also used the highlighting product on their hair around that period of time.

"I know everybody says this, but in high school, I really was the dorky kid," John once said of his high school experience in an interview with the magazine Orange Coast in 2014. He noted that during that period of his life he was more into magic and theme parks, calling his behavior very innocent. He explained that when kids his age were going out drinking on Friday and Saturday nights, he was at Disneyland, going on the rides and listening to the bands.
