Gorilla Escapes Inside ISS and Chases Crew Mercilessly

It seems that besides doing a lot of important science, and generally expanding humanity's horizons, astronaut Scott Kelly has time for a practical joke. Thanks to his twin brother Mark, Scott received a gorilla costume when the ISS was resupplied, and used it to chase his crew-mate Tim Peake around. It's a funny but effective way to celebrate a year in space.

And the Benny Hill music is a nice touch.
