That's not the one I heard.
The version I heard went like this:
There's a terran, a jenquai and a progen on a ship. Suddenly the ship's life support fails and the three are forced to abandon. Each escape pod only holds one person, and there are only 2 pods.
The jenquai stands up and yells, "As a jenquai, I am a genius, so I should be saved so my incedible brain will not go to waste." And he jumps into the port for the first pod.
The progen turns to the terran and says. "Save yourself. I can just be called forward, so there's no need for you to die for me."
The terran says "Nonsense, there's a pod for each of us. That 'genius' jenquai just jumped out the garbage chute!"
