Needless to say there are minor spoilers ahead:
1. The "F" Word: In a bizarre scene of art mirroring life, Channing Tatum's Jenko gives a drug dealer a lecture for using the offensive homophobic term "f----t" at him and Schmidt (they look like they're engaging in oral sex). It's not the gay sex in the stacks that's shocking but the fact that the "f" word is the exact gay slur Jonah Hill slung angrily at a paparazzo earlier this month (and nearly immediately apologized for on the Howard Stern radio show). The moment is shocking, because audiences will wonder if it was possibly inserted into the movie after Hill's bad press.
2. The Prison Scene: Early in the movie, Schmidt and Jenko pay a visit to the villain of the first movie, Mr. Walters (Rob Riggle), who's in prison with Eric (Dave Franco), the high-school drug dealer in "21 Jump Street." As viewers might remember, Schmidt shot Mr. Walters in the crotch, and Walters is very graphic about the fact he was left penis-less and now has a surgically crafted vagina. Walters goes on to say that he's Eric's bitch. This leads to some crass sexual allusions and gestures and is generally pretty gross humor.
3. Like Father, Like Daughter: During his stint as a college student. Schmidt meets a beautiful young woman at a student-led poetry café. After pretending to be a slam poet, Schmidt wins the out-of-reach girl's attention and eventually -- on a completely different night -- ends up sleeping with her. As it turns out, of course, she's no ordinary girl, and during Parents' Weekend it's clear that Schmidt knows the girl's father really, really well. This leads to all sorts of horrifying but humorous jokes about Schmidt "f--king so-and-so's daughter."
4. Hit Like a Girl: In a climactic scene, Schmidt and a criminal young woman get into a hand-to-hand fight that's realistically physical and possibly startling for those who've never seen a guy hit a girl on screen. They punch and kick and hit each other, and the young woman continues to taunt and punish Schmidt. But at some point, the woman begins to think Schmidt also wants to kiss, and the fight takes a surreal, humorous turn. Fans of the show "Battlestar Galactica" may be reminded of the popular series' many inter-gender boxing and fight sequences.
5. End Credits: During the end credits, which are pretty hilarious, there's one cringe-worthy scene that shows kids playing a Jump Street game that features shooting at penises. Young boys are shown pretending to be Schmidt shooting at Walters, gunning down a row of fake penises as if they were cans on a fence. That's not exactly the kind of thing you can un-see, so leave before the credit gags if you can't handle the sight of penis target practice.
