Mind over bladder funny trucker shirt, for captains, pilots, anyone who just has to hold it, no toilet break now. Great road trip shirt, perfect funny gift for truckers. Put in the miles, it's mind over matter.
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.
