Zach GZach Galifianakis created a huge furor last week when it appeared he smoked pot on Bill Maher's 'Real Time.' Earlier this week, Maher revealed that the spliff wasn't real. "If it was a real joint, Wolf, I would have smoked it ... I think it was cloves or something," Maher told Wolf Blitzer in a CNN interview. "Zach's crazy, he's not that crazy."

When Galifianakis appeared on 'Late Night with Jimmy Fallon,' Jimmy asked about the incident and whether or not the 'Due Date' star was smoking the real thing. He said, "In the entertainment business, [there's] a lot of smoke and mirrors, and there's a lot of things that aren't necessarily true or real." He then swiftly removed his mop of hair to reveal a shaved head.
