Hartman:
Left shoulder, hut! [Lawrence briefly hikes his rifle to his right shoulder, but corrects himself though Hartman notices and realizes what has happened] Private Pyle, what are you trying to do to my beloved Corps?!

Lawrence:
Sir, I don't know, sir!

Hartman:
You are dumb, Private Pyle, but do you expect me to believe that you don't know left from right?!

Lawrence:
Sir, no, sir!

Hartman:
Then you did that on purpose! You wanna be different!

Lawrence:
Sir, no, sir!

Hartman:
[slaps Private Lawrence's left cheek] What side was that, Private Pyle?

Lawrence:
Sir, left side, sir!

Hartman:
Are you sure, Private Pyle?!

Lawrence:
Sir, yes, sir!

Hartman:
[slaps Private Lawrence's right cheek; knocking his cover in the process] What side was that, Private Pyle?!

Lawrence:
[about to fall apart] Sir, right side, sir!

Hartman:
Don't f*** with me again, Pyle! Pick up your f***in' cover.

Lawrence:
Sir, yes, sir!
