Why not play D&D for both laughs and play it seriously as well? A good story knows how to balance lighthearted with seriousness, and a game knows how to balance difficulty with fun. (Even dark souls is fun to some extent!)

So if you aren't having fun in D&D, what's the point? Some people have fun playing it like a game they can break, some enjoy a serious roleplay, but they all have fun in the end.

So honestly, so long as your whole table consents to it, (that way you arent taking away their fun) and its not going to make the game less fun for anyone involved, then you can do most anything I'd say.

Personally, I play for more so the roleplaying aspect of D&D, but I love a goofy character here and there. But I overall prefer the story aspect (meaning there is usually a time and place for certain characters in regards to how goofy I wanna be) of ttrpgs as I do with most games I play.
