Shortly before the Basterds attempt to meet their double agent in the bar:
Aldo: Fighting in a basement presents several difficulties, the first of which being, you're fighting in a basement.
While strategizing their entry into the theater:
Aldo: I speak the most I-Talian here, so I'll be the escort. Donnie here speaks second most I-Talian, so he'll be your cameraman. Omar, over there, speaks third most I-Talian— Omar: I don't speak Italian. Aldo: Like I said, third best. Just keep your fuckin' mouth shut. Fact, why don't you you start practicin'!
"The Germans' nickname for me is 'The Little Man?'"
"To be honest, I'm surprised by how tall you actually are."
The best part is the look on Aldo's face during that exchange. He doesn't say a word about it, but you can see "Man, I was hoping he wouldn't find out about that," written right on his face.
A little black humour in here, while rescuing Hugo, the Basterds kill his captors in the most over the top and bloody ways. After that, while talking to him, one of the soldiers appear to be alive, and one of the Basterds answers him with a shot. Without changing expression, or looking to him. Without camera movements. Its hilarious. No, really.
