Zach and SpliffBill Maher repeatedly reminds his audience that he loves him some marijuana, but according to the host, whatever Zach Galifiankis was smoking on 'Real Time' on Friday wasn't pot.

"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."

Maher's publicist also sent a statement to E! Online saying the joint was an unspecified "prop."

However, Margaret Hoover, who was a guest on the show Saturday night, said she thought the spliff smelled real.

"Sure smelled like the real thing...," Hoover speculated on Twitter.
