With his signature intimidation bit:

Full Metal Jacket made him famous in 1987, and he’s still getting paid off of it.

I can’t get sick of this guy.

Interesting how the video refers to him as a “Drill Sergeant”, when that term is strictly Army. R. Lee Ermey was a U.S. Marine. I imagine the producers probably though “Sergeant” sounded more intimidating than “instructor”.
