WASHINGTON (Sinclair Broadcast Group) — As his year on the International Space Station draws to an end, astronaut Scott Kelly "needed a little humor" to lighten up his experience.
His twin brother, former astronaut Mark Kelly, obliged.
According to NBC News, Mark Kelly sent a gorilla costume up to Scott, which the astronaut then promptly used to harass one of his crewmates.
A video posted on Twitter shows Scott Kelly in the gorilla suit chasing British astronaut Tim Peake in zero gravity, set to the Benny Hill theme.
"Go big, or go home," Kelly tweeted.
