Have you ever bet on a fart, and lost?
You know it might stink. The important thing is, if its an SBD nobody else knows YOU did it. What the heck. Right? To have the little sucker betray you and leave a skid mark worse; a greasy, all day odorous, skid mark, well that's just wrong, Right?
Voting the lessor of two evils is betting on a fart. You know its going to stink. You're just hoping it doesn't leave a big streak of poo on your back side. It always does. You'd think we'd learn not to do it.
