Homer Simpson will be part of a sperm-in-space experiment

The Kansas City Star

Matt Groening helped design a Homer Simpson patch for an experiment going up Monday to study sperm in space. Groening is an acquaintance of University of Kansas Medical Center researcher Jim Tash, whose experiment will be launched to the International Space Station. The patch features an "astronaut Homer Simpson riding an angry-eyed, bull-headed sperm cell through outer space, complete with his tail a-wagging."
