Not a lame joke, but apropos of the apes, an allegedly true story. Armstrong, Aldrin, and Collins were put into a decompression (or decontamination maybe?) chamber on the carrier that picked up Apollo 11 (USS Wasp, from memory). Nixon flew out for a photo op. A wide, but not tall, window had thoughtfully been provided in the chamber at a convenient height for seated people to talk. Unfortunately, he's the president and they're US military - so they stood up and saluted. Then sat down again, apparently all desperately worried that they'd somehow forgotten to zip their flies...
