At a construction site on the 80th floor of a high rise building, the lone conservative on the crew was having a heated political discussion with the liberals on the project. Deciding to take a break, he called everyone over to the edge of the roof. "Did you know," he began, "that there are extremely violent invisible updrafts that are able to keep a body floating in mid-air? They only occur at certain times during the day between buildings. Here, I'll show you!" He then leaped off the side of the building, and with arms spread-eagle, floated effortlessly on an unseen cushion of air, and then gradually steered himself back to the safety of the roof. "That's awesome," one of the left-wingers shouted. "I want to try it."
"Me too," another cried, and then another, and as they leaped over the side of the roof, one after the other, they fell 80 floors straight down to the ground, SPLAT! SPLAT! SPLAT!
A crowd rushed over to witness the carnage, and while doing so, one of the spectators looked up and remarked, "Boy, Clark Kent sure hates liberals!"
