He’s channeling some dude from the hood with the “getting up in my grill” line. He’s a great actor! Most especially when he’s acting like a fool.
The show has been on a long time and is always at the top of the ratings pile, so I am not the only one watching.
Sheen’s slang does veer all over the place. He is obviously very bright and articulate, though. And, he has a great command of the language. I will give him credit for keeping his language clean.
