These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
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 much or deny much.
Les Yay: Between Sissy, Missy, and Chrissy. Some of the deleted scenes even shows the latter two making out and having sex.
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.
Nearly every other character in the movie, whether it be a celebrity cameo or a character from a previous movie.
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.
