Zach Galifianakis did ‘heroin’ on live television on Friday, taking a hit on Bill Maher’s ‘Real Time.’

Promoting his new film ‘The Hangover: Part II.,’ Maher decided to make Galifiankis live up to his hard-partying character’s ways and experiment a little with heroin.

To up the ante from Galifianakis’ infamous October appearance on the show, during which he lit up a fake joint to advocate for the legalization of marijuana, Maher took out a tray of heroin for the star, who was instantly game.

Of course, the heroin was fake, but it was another memorable TV moment for the wacky duo. And it definitely got an awkwardly-laughing response out of the audience.

We love Zach Galifianakis and we love Bill Maher. So when the two come together, its only inevitable something hilarious and outrageous was going to happen.

And it did! During the episode, Maher was discussing the legislation of marijuana with Galifianakis along with a bunch of other conservative types opposing the decriminalization of the drug.

“It’s a tricky thing politically to jump on that bandwagon [and vote for the legalization of pot] because I think that maybe people still see it as taboo,” said the ‘Hangover’ star.

Then Galifianakis pulled out a joint, lit up and puffed away. Hilarious!
