She's never played BloodBowl, on Fumbbl or elsewhere, and only occasionally does more then politely glance in my direction when I talk about it (or asks if I won after hours of ignoring my responsibilities), but....

She can kick your butt. She is significantly smarter than I am and routinely wipes the floor with my geek buddies when dragged in to round out games of whatever we are playing. So if Mothers in general count, I've got one to go for the top prize (assuming she would ever bother, say, if money was offered) :)
