London, Nov 1 (IANS) Hollywood funnyman Zach Galifianakis stunned American TV viewers Friday night when he lit up a joint and started smoking it during a political chat show.

‘The Hangover’ star was making a point about the upcoming vote for marijuana legalisation on ‘Real Time With Bill Maher’ when he took the roll-up and a lighter out of his blazer pocket, reports imdb.com.

‘It’s a tricky thing politically to jump on that bandwagon (and vote for the legalisation of pot) because I think that maybe people still see it as taboo,’ he said.

Galifianakis then started puffing away and offered the joint to fellow guest Margaret Hoover, a conservative news reporter, who smelled the cigarette and verified it was the real thing.

The funnyman continued smoking as the political debate on the show continued, and then raised a laugh by screaming: ‘Oh my God, look at those dragons!’, poking fun at the stereotype of stoners.
