NASA astronaut Scott Kelly who keeps everyone entertained and up to date on space news through his Twitter feed, decided to add a bit more levity to the environment with a silly prank. Kelly dressed up as a gorilla to surprise his (un)suspecting colleagues, whom he hilariously chased around the International Space Station. In his own words, “Go big, or go home. I think I’ll do both” and he certainly did. But the question remains, where does one find a gorilla costume in outer space?
