Why are girls lacking in sense of humor?

Ofcourse,I dont mean to say that girls arent capable of humor and cracking good jokes.They can come up with good jokes

I dont mean to do any gender stereotyping and if you do feel like that I’m sorry, no offense intended

But generally in a group of friends, I havent noticed girls initiating humor, or being the stand out comedian, they always add to the drama but not playing the sheet anchor like how guys have been observed to do

Also we know guys falling for girls for their so many qualities – beauty, their intelligence,their attitude and so on….humor has never been heard or should I say very rarely heard as one of those qualities.

Is it because they take down the worries of others onto themselves that they are unable to bring out their lighter side?
