It seems that tabacky wasn't so wacky when Zach Galifianakis lit up during a recent appearance on HBO's "Real Time With Bill Maher."

Discussing California's Proposition 19 ballot, which seeks to legalize marijuana possession for personal use, "The Hangover" star pulled out a joint, lit it, and began puffing away as his fellow panelists sat stunned.

Though conservative television and radio commentator Margaret Hoover sniffed the cigarette and assured viewers, "It's real," Maher's publicist has since told celeb site RumorFix, "It was not an actual joint. It was a prop."

In fact, Maher himself told CNN's Wolf Blitzer in an interview on "The Situation Room," "If it was a real joint, Wolf, I would have smoked it…I think it was cloves or something. Zach's crazy, [but] he's not that crazy."

California voters will decide on Prop. 19 today.
