As far as the male of the species goes:
Three Stooges Gene: Rarely dominant in females, can make males ‘hoot and holler’ at the sight of people getting hit with hammers and wooden planks.
Tool Gene: No, not the band who makes creepy videos, but the Black & Decker variety. Can make a grown man rip apart the Sunday paper just to get to the Home Depot flyer.
Flatulence Gene: Affects males of all ages.
I’m sure there’s more, but I’m no scientist.
