Apparently, women usually dislike scratching. I don't mean of your nether regions either. They might tolerate the occasional brief scratch of an itch, but consistent scratching drives most of them nuts. "Why are you SCRATCHING all the time?".
You also cannot play baseball with scratching, including the aforementioned nether regions. You certainly can't hit a slider without scratching.
They also tend to leave you alone if you are, um, animated when a play happens. It doesn't even need to be more than a run off tackle for 3 yards. Just jump up and shout at the TV that the tight end was clearly down field and the safety was in cover two and that SHOULD HAVE BEEN CALLED and I CANNOT BELIEVE THEY MISSED THAT!!!!!
Do that about every third or fourth play, unless of course they actually understand football in which case you'll need to be more creative.
