Though, you have to keep in mind. Not everyone wants to play D&D and be super cereal and cool.

Sometimes people just want to mess around.

Hence things like lusty Bards, murderhobos, 3 INT Barbarians who cannot communicate with anything, people homebrewing crazy OP things etc.

It's an aspect of D&D that can't be discounted. The ability to do what you want, allows people to joke around. This ranges from the game derailing murderhobo streaks (And subsequent "Rocks fall and everyone dies" DM responses), to things like playing silly characters but in a reasonable way (Like for example Sir Bearington)

Not everyone likes to play this way, many like a more serious approach. But it's popular enough to create pop culture references to the types of players who do that stuff.
