The Humor of the Sexes

Whenever I am flying on Southwest Airlines and hear a male voice over the loudspeaker, my ears perk up and I begin to pay attention, hoping for some humor to lighten the dreary repetition of safety instructions for flying.  I fly so much these days that I could give the safety instructions myself—almost word-for-word if my memory worked that way rather than having been trained to forget useless information.  Hence if I hear the usual rigmarole spouted out with scarcely a pause for breath, I zone out nearly immediately.

Very rarely—once perhaps in all my flights across the country—has a woman made jokes.  Nearly always it is the men and the majority of them do try to be funny (at least on Southwest).  My question is this: why?

Yes, why are men funnier than women?

Perhaps it is because women are typically more focused on nurturing and therefore care more for the travelers' attendance to safety than in trying to make them laugh.  Perhaps they are afraid that one passenger who had never flown before might be alarmed at being told that nitrous oxide would flow from the oxygen mask.  Perhaps it goes against their nature to boldly state that any passengers who do not like their service can use any of six emergency exits.

Or perhaps it is because men have more confidence in their ability to be funny.  Women are often more perceptive and more concerned about how others will receive their words and actions, humorous or otherwise.

Then again perhaps it is some other reason entirely.  What do you think?
