Bee Movie. In one scene, the main character bee, Barry, says "Gonna go drain the stinger" or something along those lines. That's creepy enough. But it gets worse when the other bee stings the fat guy in the courtroom. When Mr. Main Character Bee asks him what it was like to sting someone, he answers: "It was like your adrenaline pumping like crazy, and then... ecstasy." Considering that fact that stingers had ALREADY been hinted at as being something... (ahem) more than stingers, this just gets even creepier. Plus, he stung that dude in the BUTT.
...aren't bees supposed to die after they sting someone?
Actually, the reason he didn't die was because they replaced it with a cocktail sword before it was too late.
Near the end of the movie, a large amount of bees form a black-and-yellow target for Barry to land the plane on. One can only imagine how many bees were crushed by the plane's wheels...
This might not entirely fall under Fridge since its blatantly pointed out in the movie (along with "the evils of humanity" being slightly exaggerated) but in-universe at least bees are sentient world wide, and either raised in captivity constantly being drugged for their honey (kept bees) or the majority of a colony being to afraid to leave the hive for fear of getting swatted or stepped on, the amount of abuse Barry goes through throughout the film as well any hit hard enough to do serious damage would likely have them suffer a slow agonising death.
