Scene from the movie American Pie.

Cast of 'American Pie' reunite 20 years after the first movie was released

This one time at band camp, we met a group of teenagers who vowed to lose their virginity before their high school graduation.

It's hard to believe, but that one time at band camp was 20 years ago! Yep, that's right. It's been two decades since the first American Pie film was released, and we were introduced to Jim, Kevin, Oz, Finch, Stifler and the rest of the gang.

Luckily for us though, the cast has come together for an epic reunion!

This week, Entertainment Tonight brought Jason Biggs (Jim Levenstein), Chris Klein (Chris "Oz" Ostreicher), Tara Reid (Vicky Lathum), Alyson Hannigan (Michelle Flaherty), Eddie Kaye Thomas (Paul "Sh*tbreak" Finch), Seann William Scott (Steve Stifler) and Natasha Lyonne (Jessica) together for a two-part reunion special - and all of a sudden, we feel like we're back in 1999.

They've all sure grown up. According to ET, instead of discussing the best way to get laid, now the actors talk "about moving to the suburbs to spend more time with their families and their commutes, about golf games and turning 40, date nights and engagements and marriages and is anyone planning to have more babies anytime soon?"

"Whenever I see this group it just really takes me back and it feels like no time has passed," Biggs said in the interview.

The 41-year-old also opened up about that iconic apple pie scene, admitting that it was this bit of the script that made him really want the role.

"I just thought, 'Oh my god, that’s amazing. I’ve never read anything like that. I’ve never seen anything like that.' And I remember saying to myself, 'God, I really hope I get this part. I really want to do that.'

"The day of filming this scene, I had a complete freak-out and I called my manager in my trailer and I was like, 'Am I really going to do this?' And he was like, 'You f**k the sh*t out of that pie.'

"I had one moment of freak-out, like, 'What if no one sees this? What if absolutely no one sees this and I f**k a pie for no other reason than I got paid very little money to f**k a pie?' I kind of freaked out, but then he gave me a vote of confidence and I went in there and I did it. And I did it hard and I did it good and I did it long."
