This is one of those videos that makes you laugh uncontrollably, yet you're not quite sure why. Here, Beyoncé sits with Britney Spears, Lady Gaga and Rihanna as they go through their Number Ones—until an uninvited guest interrupts.

You may know Aubrey Plaza from Parks and Recreation, but she also does some mean stand-up, here she is with a spot on Sarah Silverman impression.

So, let's try something new! Each weekend I will be posting a humorous example of sketch comedy that you can watch. Here is today's installment. It is from the funny British sketch show "Big Train," featuring Simon Pegg.

This sketch comes from season 3 of consistently butt-gusting Mr. Show. David Cross has seemed to master the art of the comedic nervous breakdown and the old guy sitting next to him mastered the art of being emotionless and elderly.

Robin Williams knows drugs. He's done many different varities and has even had a stint or two in rehab. Listen as he describes their effects.

Pitching a movie to a big time studio executive must be a scary and stressful process. Eliminate shirts and any semblance of a coherent movie idea and it can turn into a sublimely absurd process.

Tonight on Chelsea Lately, Chelsea Handler and her panel discussed how humiliating Dancing with the Stars is for all involved. The topic of Kate Gosselin also came up, and Handler couldn't help but mock ex-husband Jon's minature-sized member. Video inside.

Tonight, Stephen Colbert gave his hilariously satirical take on the ugly-as-hell new $100 bill. Mocking the Treasury for its over-the-top presentation, Twitter for its inability to make money, Taco Bell, and more, Colbert covered all of the bases. Video inside.

Tonight on The Daily Show, everything was gay, gay, gay! First, Jon Stewart discussed how President Obama was heckled for not yet repealing 'Don't Ask, Don't Tell' (ugh). Then, a crazy man attacked Senator Lindsey Graham's sexuality! Video inside.

Recently, Jon Stewart said, "Go fuck yourself" to Fox News. Then, Bernie Goldberg attacked Stewart. Tonight, Stewart responded, issued his own attacks at Goldberg and Fox News, and said, "Go fuck yourself" again (with a gospel choir). Videos inside.

Media is not the only glamorous field in which you can work for free. The entertainment industry wants your free labor as well. Break into the prestigious world of HBO comedy, using only your own wits and indentured servitude!

Yikes. You know things won't end well when one starts a proposal video to his girlfriend(?) with, "I'm not the type of guy that's going to cut his hand if you don't love him." The full train wreck, inside.

Tonight, Stephen Colbert did a scathing exposé of President Obama's communist-like bowing via footage of Obama bowing to international leaders (and even his own dog). To Colbert, Obama's bowing is yet another example of how the terrorists are winning.

Tonight, Jon Stewart took Fox News to task for its focus on the Nuclear Security Summit's logo and assertion that it was a crescent moon/nod to muslim countries before giving the network a taste of its own medicine. Video inside.

Conan affects a cockney British accent to cover Radiohead's 90's classic during a soundcheck in Eugene, OR. Those high notes are a job better left to Thom Yorke, but he's clearly having a blast on his new tour.

Check out this sketch from everyone's favorite Canadian parody news show This Hour Has 22 Minutes. If you are unfamiliar with this show don't feel bad. I mean the only Canadian show Americans really watch is Degrassi. It's a fact.

Tonight, Jon Stewart overviewed the media's reaction to a report that many poor households don't pay federal income tax before comparing it to the non-reaction over the fact that Exxon Mobil also doesn't pay. Inside, video of Stewart's magnificent juxtaposition.

G4 network alumni and host of 'Web Soup' Chris Hardwick, sometimes lends his comical expertise to Chelsea Lately's roundtable panel. Here, Hardwick discusses annoying people on twitter and the word "retarded."

This week has been an arms race for late-night hosts doing jokes about KFC's new double down "sandwich". In this clip, Craig outs a very odd looking Paul McCartney as a meat lover.

In a Eugene concert, on his Legally Prohibited From Being Funny On Live Television tour, Conan O'Brien sang a rendition of I Will Survive that will help the most die-hard Coco fans make it through to next November.
