who's smarter?

Getting ready to go to work this morning, my husband comes out with his wallet, phone, and pocket knife.  "Ok, I'm ready," he says.  "What about your keys?"  I asked.  He disappears for a minute and then reappears.  "You know how they have in sitcoms, where the man feels threatened if the woman is smarter than him?  Well I got it," he declared.  "If my wife wasn't smarter than me, I'd be dead!"
