- [to Kahmunrah] Two words come to mind when I hear you speak: delusional and weirdo. And If I had to pick a third... goofy. Just plain goofy.
- [to the fleeing Underworld army] Adios, Birdbrains!
General Custer 
- We're Americans. We don't plan, we do!
- [when the tablet doesn't open] I'm afraid Mother and Father might have slightly changed the combination on me.
- [to Darth Vader] Is that you breathing? Because I can't hear myself think! (Vader is trying to force choke kamunrah) What is this? (Kahmunrah imitates the gesture) You've lost me. Can I give you advice? Just simplify; there's just too much going on. You're evil, you're asthmatic, you're a robot. And what is the cape for? Are we going to the opera? I don't think so. Sorry. Goodbye.
- (When his army of the Hawkmen gets wiped out by Lincoln) Well, this is awkward.
- Larry: I'm sorry. Last time I checked, I thought we lived in a free country. So...
- Brundon: No, we don't.
- Larry: No?
- Brundon: It's the United States of "Don't Touch That Thing Right in Front of You."
- Capone: How come you're wearing a dress?
- Kahmunrah: It's not a dress. It's called a tunic. It was the latest fashion in 3000 B.C. Are there any other questions?
- Ivan: About this dress, do we have to wear one too?
- Kahmunrah: No. I've already explained to Mr. Al Capone. It's not not a dress; it's called a tunic. There's quite a difference.
- Larry: You know how you were telling me that the key to happiness was something, but then the sun came up? I think I figured it out. It's doing what you love, with the people you love, isn't it?
- Teddy: Well, I was going to say physical exercise, but the love thing's good.
- Kahmunrah: [defeated by Larry] What are you?
- Larry: I'm the nightguard.
- [he pushes Kahmunrah into the Underworld]
- Kahmunrah: NO!!!
- Tuskegee Airman #2: Ma'am, I'd just like to thank you.
- Earhart: For what?
- Tuskegee Airman #2: Well, a lot of people didn't think we could fly, either. Thanks for clearing the runway. [salutes]
- Earhart: Do you know why I became a pilot?
- Larry: I have no idea.
- Earhart: For the fun of it. Why else would anyone do anything?
- [after defeating Kahmunrah]
- Custer: The Battle of the Smithsonian. The greatest battle the world will never know.
- Larry: We'll know.
