The "Zero Gravity Toilet" instructions are alleged to be the only intentional joke1 in Stanley Kubrick's 2001: A SPACE ODYSSEY.

Dr. Floyd
reads the ZGT instruction panelThe instructions are seen only momentarily during Dr. Heywood Floyd's flight to the Clavius base on the Moon. Aboard the Aries spacecraft, he's seen sleeping2, enjoying a meal and schmoozing with the (presumed) commander of the craft. And, during one brief shot, he anxiously reads these instructions.

According to Jerome Agel3, these instructions4 were authored by Frederick I. Ordway III, the "Scientific Consultant"5 for 2001. The text for these Zero Gravity Toilet instructions are taken from Agel's book.

As you can see, they're not only remarkably detailed, but they actually describe a plausible lavatory suited for "Zero G" flight. For all we know, very similar instructions are posted somewhere on NASA's Space Shuttles, which are descended from the same designs upon which 2001's Pan Am space clipper was based.
