Your image of the show is pretty distorted, it’s not at all some edgy middle schooler show. The humor is (generally) in how much of a dumbass Michael (the boss) is and how much he ruins situations trying too hard to be funny, and the witty jokes are generally well performed one liners by Jim (John Krasinski) or malapropisms by Michael, like “I’m not superstitious, but I’m a little stitious” or “his cap was all pitated!”
The show repeatedly makes fun of Michael’s prejudice, too, like how he feels superior to the warehouse guys despite having the same education as them and not even earning that much more. It isn’t edgy to make fun of the stereotypical middle-aged white male boss being insensitive
