Not only is it funny (with overtones of pitiful), it gets a rise out just about everyone who cares to erect an objection. Rigid, upright individuals, blood flowing copiously to their heads, cocking their virtual pistols and ready to shoot the first time someone rubs them in a manner that provides enough friction. It's a penetrating form of humor, a kind of humor that some have to stretch to get, especially those who are anally retentive. For others, it's just plugging along as usual, strapping on the first thing they come to, and then using it to probe everyone within reach. I don't know why it's got you so inflamed. Me, I'm having a ball sacking the opposition. I can't do it all the time (I'm old) but I find it satisfactory to work in spurts. And while my youth is gone, at least I can remember it as not so much checkered, as spattered. Because the rubber didn't always meet the rode, y'see.
