I wonder what the one hand has against the other. It must be a psychological thing. Probably the one hand is jealous of the other because the one doesn't have to wipe or something. I'm sure his hand deserved it.
I doubt it's that simple, Mackey. The hand that has to wipe likely sees more action elsewhere than the other. Both actions probably cancel each other. Sometimes it just sucks to be the dominant hand ... "Do I have to do EVERYTHING around here? Sheesh ..."
