Evil Is Sexy: The jewel thieves, from the tight leather catsuits to a scene of them dancing around in their underwear...
Genius Bonus: Sissy refers to Jay and Silent Bob as "Little Boy and Fat Man", the code names given to the two atomic bombs dropped on Japan.
Hilarious in Hindsight: Will Ferrell's character is named Marshal Willenholly, a reference to the TV show, Land of the Lost. Seven years after this movie came out, a film version of Land of the Lost was made starring Ferrell.
Ho Yay: Jay likes to constantly remind everyone within earshot that he likes the ladies, then he or Silent Bob says or does something suggesting that he is deep deep in the closet. Silent Bob is guilty, too, only he doesn't say or deny much.
Les Yay: The jewel thieves are supposed to lesbians, according to Kevin Smith — however, many of the scenes that would have made this even more apparent wound up on the cutting room floor. They can still be found on the deleted scenes of the DVD.
Well more like Two-Scene wonder: The Sheriff. He has no problem making the Federal Wildlife Marshal look stupid by correcting him about the difference between monkeys and apes. Later on he is the only one that doesn't fall for Jay's ruse of sneaking the monkey out as their adopted kid. He also leaves the Marshal to deal with Jay and Silent Bob without any assistance. Finally he mocks the Marshal's compliment during the scene with the rules. Why is he able to do that? Because he is John "Fucking" Bender, that's why. (And alsoRodimus Prime.)
Seann William Scott as Brent. In his one scene, he sings a ridiculous song told from the point-of-view of a rabbit, gets outed by Jay for being a sheepfucker, and is then promptly tossed out of a moving van.
Also Carrie Fisher (a.k.a. Princess Leia) as a nun who gives the duo a lift early in the movie.
Pandering to the Base: Kevin Smith admits that he made Jay And Silent Bob Strike Back purely for his fans who wanted a Jay and Silent Bob movie with tons of references to his other films, as well as lot of swearing, crude jokes, and Fanservice.
