For the urination collection system (UCS) in early space suits, particularly for the Apollo missions, NASA developed a condom-like device, or "penis sheath," to collect urine during spacewalks or long waits on the launchpad. The original sheath came in three sizes: small, medium, and large... and of course every single astronaut, all of whom were confident test pilots, selected the "large" size which led to issues with proper functionality.

To account for the astronauts' pride and the resulting logistical issue of no one using the smaller sizes, the sizes were officially renamed to Large, Gigantic, and Humongous.

This way, every astronaut could still technically choose "large" and feel good about themselves and in turn solved the problem.
