Barry Humphries' appearance on the ABC's Q&A program sent twittersphere abuzz last night night - proving what most Australians already know, that he's one of the nation's greatest comedic talents.

Humphries joined Oscar-nominated actress Jacki Weaver, author and Fairfax journalist David Marr, former federal Liberal leader John Hewson and award-winning British actress Miriam Margolyes (The Age of Innocence, Harry Potter) on the panel.

Laughs were drawn from the first words Humphries uttered when asked by host Tony Jones if he had any thoughts on the issue of foreign labour in Australia's mines.

"Very few I must say," was his reply.

Humphries then referred to Australian mining magnate Gina Rinehart, who according to BRW is the world's richest woman, and made a comment about her hair.

The buzz on Twitter took off.

"Barry Humphries#qanda excellent Anna—la Tickel" wrote one online viewer.

"Every time Barry Humphries pauses, my heart stops, for fear that his has," tweeted comedian Dave Bloustien.

"Barry Humphries is my idol. I adore him," comedian Julia Morris tweeted after the show.

"Is there a funnier Australian than Barry Humphries? I think not," tweeted journalist Tom Steinfort.

"Q&A last night proved Barry Humphries is still a genius," a viewer tweeted.

Even columnist Joe Hildebrand added to the twitter conversation: "I don't know what Barry Humphries was drinking before the show but somebody please give him more."

The satirist also touched on the Craig Thomson affair currently enveloping Australian politics, calling the member for Dobell a "liar and a ratbag". He then hit out at A Current Affai-r's plan to air an interview with a Sydney escort.

"I deplore, well it's moving on to another theme, a famous television network like Nine and their actions in paying a prostitute an amount money like that to, sort of, sing like a canary," Humphries said.

He then went on to compare the A Current Affair story with another involving his friend Clive James.

"In the same way as another well-known television magazine program, door-stopped my friend Clive James quite recently and produced some floozy and humiliated him in the street. They flew this woman across the world for this deplorable, disgraceful piece of television. Something serious is happening," Humphries said.

Humphries' appearance on Q&A comes before his Eat, Pray, Laugh tour, which starts next month.
