Mo Mandel: Negative Reinforcement

Several comic greats pay tribute to the legendary stand-up stage founded by Budd Friedman in 1963.

BE MORE CYNICAL was originally aired on HBO, and offers viewers a chance to see Maher's full routine, which sees him tackling a wide array of topics, and leaving the audience recoiling in laughter.

Political comedy about the Government (domestic and foreign policies), the president, the public's own ignorance and faults, and so forth. He also makes some hilarious detours in his own renditions of rap lyrics read out in proper, coherent (non-Ebonic) language. There are also some very poignant pieces on Bush, religion, drugs (notably marijuana), which then link to homeland security. Unlike a comedian like George Carlin who may go from topics in the 'big world' in his act to things in the 'little world' like spotting the random things in life, Maher is very much a comedian of the times, on the attack but clear about his political allegiances.

Maher addresses contemporary political, social and cultural topics -- Iraq, President Bush and the so called Axis of Evil. The opinionated Maher said about Victory Begins at Home: "We've heard everything about the War on Terrorism except what we can actually do to help win it. The government used to do that for us through propaganda (the positive kind) posters, so taking my cue from the great old posters of World War I and World War II ('Loose Lips Sink Ships,' 'Buy War Bonds,' 'Plant a Victory Garden,' etc.) I commissioned artists to paint the posters our government today should be putting out to help us win this war."

Declared to be the funniest Robin Williams video made, this is a don't-miss comedy.

George Carlin brings his comedy back to New Jersey and this time talks about Offensive Language, Euphemisms, They're Only Words, Dogs, Things you never hear, see or wanna hear, Some people are stupid, Cancer, Feminists, Good Ideas, Rape, Life's moments, and organ donors.

When George Carlin is asked which HBO concert is his favorite, his answer is always, "Jammin’ In New York." The show, taped at the Paramount Theater in Madison Square Garden and winner of the 1992 CableACE Award, is a perfect blend of biting social commentary and more gently-observed observational pieces.
