Well, I left out the sarcasm tag. Sometimes Im just too subtle for my own good...
I feel strongly about this one because when I got married, I basically had to teach my wife how to cook. During my bachelor years, I developed some serious kitchen skills. Working in a restaurant for a couple of years helped as well.
I also kept a very clean and tidy apartment. I didn't stress that part with my wife quite as much.
Bottom line, every man should know how to cook and clean for himself. The image of a "helpless man" sitting hangdog on the couch in his underwear because the wife (or mother) isn't around to care for him annoys me. Ain't nothing manly about that.
