OK, so now I'm reading the movie quotes for FMJ off IMDB and this line cracked me up so bad because I got the exact same line in boot camp and I started laughing then too....(except it wasn't so funny what happened when I laughed)
Gunnery Sergeant Hartman, Drill Instructor: What's your excuse?
Private Cowboy: Sir, excuse for what Sir?
Gunnery Sergeant Hartman, Drill Instructor: I'm asking the fucking questions here do you understand?
Private Cowboy: Sir, yes Sir!
Gunnery Sergeant Hartman, Drill Instructor: Well thank you very much, can I be in charge for a while?
Private Cowboy: Sir, yes Sir!
