I didn't really think this was a comedy. SPOILER
This is the only part I thought was funny.
Walter: (holds up the card) Well I'm a fleet admiral. And I'm telling you to hit the road.
Astronaut: I'm sorry sir. I didn't realize you were a fleet admiral. As a matter of fact, (pulls out card) I'm a fleet admiral too! It's just a card, Bugnuts! It doesn't mean anything!
But I didn't really find anything else funny. Except maybe the robot.
