An example of real humor, courtesy Paul Krasner, founder of the now defunct Realist magazine

Krasner is perhaps best-known for The Realist's fold-out cartoon of all the Disney characters performing every possible sex act on one another.

After that, he is probably best-known for conjecturing that on the plane back from Dallas, Johnson was busy fucking JFK's corpse in the neck to make an exit wound look like an entry wound.

But my personal Krasner favorite was a throw-away of his. You see, around the time of the first manned orbital space flights, there was still a laxative-type product called "Serutan", a name that was picked solely so that the slogan for the product could be: "Serutan - it's "Natures" spelled backwards."

And there was another product called Tang - powdered frozen orange drink crystals which NASA had developed specifically for use by the astronauts.

Trouble is, Tang made the astronauts gaseous and they reported this tendency toward flatulence to NASA mission control.

Whereby Krasner had, in the next issue of The Realist, a statement to the effect that Tang is Fart spelled sideways.
