We already knew that Chael Sonnen was borrowing heavily from pro wrestling for his promos but last night (Sat., Jan. 28, 2012) after his unanimous decision win over Michael Bisping, he outright stole an old promo from "Superstar" Billy Graham.

When Joe Rogan climbed inside the Octagon to ask Sonnen a question for the post-fight interview, Sonnen simply took the mic and did his thing.

Or I should say, Graham's thing.

This is a new low for Sonnen, whose schtick is so unbelievably tired, I can't imagine it will hold up for much longer, especially now that folks know he's straight up ripping off old pro wrestlers promos from way back in the day.

Above you can watch Sonnen's version but after the jump check out the original, from someone who actually knew how to cut a promo.
