Hope you're feeling nostalgic, because we're going back in time!
With "Monsters University" hitting theaters this weekend, we get a look at Mike Wazowski and Sully in their college years.
But we also decided to do a little digging of our own -- seeing what stars John Goodman and Billy Crystal looked like back in the day and finding out some of their own off-kilter adventures in higher education.
"I could have been better," Crystal tells toofab about his time at NYU. "I was always looking for something else to do, I could study last minute and get a solid grade, but I really could have been a good student."
But Billy definitely had a unique experience. Not only were his classmates people like Christopher Guest and Michael McKean, but his film class was taught by Martin Scorsese!
"Nobody was who we were yet," he says of his famous classmates. "[Scorsese] was a very intimidating young guy, hair to his shoulders, big thick beard, making his first movie. We'd watch movies and then he would talk about them. That was inspiring."
"I ain't never been in no college with famous people like Billy here," Goodman (who attended Southwest Missouri State University) jokes.
"I was a drifter for a while, I just was desperate to fit in with a group. I was lost, treading water, trying to find my way," he adds. "I wanted to play football. It didn't work out. I didn't really know what I wanted until I found acting in a theater department. Everything fell into place and I had a passion about something. Then, I started living my life."
Charlie Day, who voices Art in the flick, had sporting dreams too while attending Merrimack College in Massachusetts ... with equally disappointing results.
"I went to college to be a jock and to play on the baseball team," he tells us. "I got cut and realized that that was it for that. I was really small, the guys were really big on that team."
"Then I was a bit of a theater nerd, I did plays, I was a art history major and I was a decent student but I also probably partied a little too much," Charlie adds. "I experimented with things and with ways of thought and it was a great experience for me."
Goodman actually celebrates his 61st birthday today -- but he still had his trademark smile right out of high school in the photo above.
