Did you know about this funny habit of Cosmonauts ?
(For the uninformed, Cosmonaut is the less arrogant name for people flying into the cosmos.)
When Yuri Gagarin was about to crawl into the hand-made bullet to be shot in space, he took a leak at the right rear wheel of the bus that brought him to the rocket.
Nowadays every cosmonaut takes a wizz at the bus wheel for good luck. Them Ruskies aren’t that uptight afterall :o)
