Forrest: "I made me a promise to Bubba in Vietnam that as soon s the war was over, we'd go in partners. He'd be the captain of the shrimpin' boat, and I'd be his first mate. But now that he's dead, that means, I got to be the captain."
Lt. Dan: "A shrimp boat captain."
Forrest: "Yes, sir. A promise is a promise, Lieutenant Dan."
Lt. Dan: "Now hear this! Private Gump here is gonna be a shrimp boat captain. Well, I tell you what, Gilligan. The day you are a shrimp boat captain, I will come and be your first mate. If you're ever a shrimp boat captain, that's teh day I'm an astronaut!"
