Men & Women

As I'm watching TV I keep seeing this Expedia commercial. The one where the guy sees himself at the poker table and then his wife asks him to change the toliet paper...

Now that I'm about to embark on the married life to a woman who is light years more practical than me I wonder if that really is the way of the world. Are wives more practical than husbands? Is that the case everywhere, or is it an American thing? Is this a new phenom or is this old news?

I remember TV shows like "I Love Lucy" where the wife was the ditsy one. Has that changed?

Just wondering.
