[A young long haired Jenko notices a young Schmidt in his Slim-Shady in the school hallway]
Jenko: You're a fucking nerd.
[Then it cuts to Jenko sitting in his principles office]
Principal: Boy, you're even lucky you graduated.
[Next it cuts to the police academy with Jenko slamming Schmidt to his back on the wrestling mat]
Schmidt: Fuck! You're good at this, huh?
Jenko: Yeah.
[Next it cuts to Jenko failing his test and Schmidt passing with top grades]
Jenko: You're really good at this?
Schmidt: Yeah.
Jenko: Hey, you wanna be friends?
[We see them training together and becoming friends as they graduate the academy]
