Rajesh: Dude, if you're going to be an astronaut, you need to pick a cool nickname.
Howard: I don't get to pick it, the other guys have to give it to me.
Rajesh: Huh. If I had one it would be, Brown Dynamite.
Howard: Are you not listening to me? The other astronauts have to give you your nickname.
Rajesh: Are you not looking at me? I am Brown Dynamite!
Howard: I got pretty exciting NASA news today. Next week I fly to Houston for orientation and zero gravity elimination drills.
Penny: What does that mean?
Bernadette: He's gonna learn to poop in space!
Howard: Open the pod bay doors, Hal!
Rajesh: Maybe your nickname should be Brown Dynamite.
