Two little men in spacesuits were walking through the corridor when they spotted the body of their dead crewmate.
The crewmate's corpse lay there, decomposing.
Spacemen just kept staring at the body, completely clueless. After a long while of just standing and staring, one of them finally said something.
"This dead body goes hard."
He laughed, the other one laughed.
The dead crewmate just kept lying on the floor, rotting away.
