President Obama showed little patience for a protester who interrupted him at a White House Pride Month reception on Wednesday, immediately waving a finger and scolding, “Nonononononononono, no, no, no, no, no, no, no, no.”

With two more women coming forward Friday to accuse Bill Cosby of rape, the total number of sexual assault allegations against the famed comedian is nearing 40. He's still performing, but not without getting heckled at every turn.

Russell Brand named his most recent comedy tour The Messiah Complex Tour, so it stands to reason that he is not one to suffer hecklers gladly.

A group of protesters interrupted President Obama's health care speech in Boston this afternoon, shouting “ “Mr. President, [inaudible] Keystone XL! Stop climate change! For our generation! Stop the pipeline!”

Two weeks ago, President Obama was heckled by anti-war protester Medea Benjamin during a speech about drones and national security. The president handled it respectfully enough, acknowledging Benjamin and saying her “voice...is worth paying attention to.” Tuesday evening, Michelle Obama faced a similar situation when her speech during a Democratic Party fundraiser was interrupted by activist Ellen Sturtz from LGBT rights group GetEqual. The First Lady's response was...not quite as graceful as her husband's two weeks ago.

Except for that one clip of the two teenage girls fighting out back in the circle pit while the mother encourages them on, this one from a Newt Gingrich rally is about as good as videos of annoying Floridians being annoying (at length) come. This lady shows up and heckles Gingrich monotonously and without interruption for minutes — the first couple of which Gingrich engages her — while she staves off everyone calling her a moron, an asshole, and so on, until the camera is swatted away.

Just as Massachusetts Senate candidate and liberal deity Elizabeth Warren was getting into a meeting with volunteers in Brockton last night, a decidedly unfriendly heckler rose up and started hurling accusations — and what experts are calling a "gender-based epithet"!

After initially announcing that he'd attack her again if he had the chance, angry drunk Stephen Hanks has apologized for telling Bristol Palin that her mother is a "whore" and "white trash." His lawyer released a statement to E! News:

For a whole second time in a matter of weeks, we have footage of robotic old Northeastern Rockefeller Republican Mitt Romney raising his voice, in a public forum. This is not how your governess trained you to behave, Mittens.

Well, it's over: Rep. Anthony Weiner announced his resignation without his pregnant wife, Huma Abedin, at his side. He was interrupted repeatedly by determined hecklers and sped out of the room after his four-minute speech.

Massachusetts congressional candidate Sean Bielat had an unusual backstage exchange last week with James Ready, longtime partner of Bielat's opponent, Rep. Barney Frank. Ready snapped photos and told Bielat to "get used to" the attention. Bielat was confused! Video below.

New Jersey Gov. Chris Christie was in California yesterday stumping for Meg "$$$" Whitman, when guess what happens? Another goddamn heckler interrupts and starts offending Meg Whitman's honor! Luckily, Chris Christie was there to intervene and chew out the vulgarian.

The gays sure enjoy heckling Barack Obama at fundraisers when they're angry. Last night, for the third time in six months, a "Don't Ask, Don't Tell" protester did just that, in New York. And another heckler yelled about "AIDS funding."

Ben Konop's a jaunty young fella running for mayor of Toledo. He went to tape some photo-op and was relentlessly heckled to distraction by some dude just sitting on a porch, saying "boo" for no apparent reason, as you'll see in the video clip above, which is well worth watching. According to ABClocal:

When you're a professional entertainer—particularly if you're one of the Unfunniest Comedians in America—you have to know how to handle hecklers. Dane Cook, as you see here (click to enlarge), responds to a mere MySpace heckler by calling her "ugly like a trout." His reaction is ineffective, inefficient, and fails by every standard of the Heckler-Handling Handbook. Observe:
