Karl Malone is crazy. How crazy? So crazy that he once tried to knock Isiah Thomas' head off. So crazy that he attempted to take Kobe Bryant's wife from him. So crazy that he still uses a flip phone. So crazy that he…shaves his head with a pocket knife?

Yes, it's true. Malone and Charles Oakley made an appearance on WFAN's Boomer & Carton show this morning. During their interview, Malone was asked what he uses to shave his head. And he confirmed that he's batsh*t crazy by revealing his razor of choice.

"My pocket knife," he said, "and it's sharp."

Um, okay...
