I watched the Pats/Bucs Preseason game with my wife 5 years ago on our honeymoon. She had never paid attention to football. During the game Teddy Bruschi flipped over the offensive line, landed on his bum, then got up and sacked Brad Johnson. Now she loves Bruschi more than me.
She has also destroyed me in fantasy football two years in a row now.
Moral : Be careful what you wish for. Having a wife that doesn't understand football can be miserable. Having one that humiliates you with her knowlege of it is equally painful.
