When you gotta go go, you gotta go! An Astronaut who just can't hold on anymore. This astronaut is facing away, floating weightless. His shirt is un-tucked from his space suit and you can see the top of his butt crack. A stream of weightless urine can be seen floating off into space. I drew this as a bit of fun for kids, but any sci-fi geek (or someone with a weak bladder) might get a chuckle out of it.
