Meghan McCain has successfully scared a conservative blogger into silence.

Saturday Night Live opened its 37th season tonight with a parody of Thursday's Fox News/Google Republican presidential debate. Despite being too long and wrought with cliche—Newt Gingrich has a huge head! Michele Bachmann's eyes are crazy!—the sketch managed to work thanks to Bill Hader as debate moderator Shep…

Even though there was once a question of whether the music video for Weird Al Yankovic's "Perform This Aay"—a parody of Lady Gaga's "Born This Way"—would ever see the light of day, it hit the web today. Here it is in all its Madonna-referencing, outfit-changing glory.

The death of World Net Daily editor Joseph Farah's doubts about the legitimacy of President Barack Obama's birth certificate has been greatly exaggerated.

From time to time on Late Night, Jimmy Fallon graces us with 'Jersey Floor,' his 30 Rock-set Jersey Shore parody.

Weird Al Yankovic recently recorded "Perform This Way," a parody of Lady Gaga's "Born This Way," after the pop diva demanded to hear it before allowing him include it on his next album. But in a blog post today, Yankovic angrily revealed that Gaga had put the kibosh on his homage. Or did she?

When Rebecca Black's "Friday" first came out, you probably didn't think a music video could get any worse. You may feel different after watching this Christian parody version, titled—what else?—"Sunday." [via Urlesque]

We've previously lauded Andy Samberg's Nicolas Cage impersonation from SNL. Well, tonight, Samberg-as-Cage was back—with a very real Jake Gyllenhaal, who delivered the line of the evening: "You're in every movie—you're like the white Samuel L. Jackson."

Drama 3/4 Productions cast G4TV dream-girl Alison Haislip in this spot-on parody of Red Riding Hood and the Twilight-inspired trend of turning old legends into oversexed PG-13 horror films for fantasy-obsessed tweens. Has porridge ever been this sexy?

Tonight, 30 Rock returned without Tracy Jordan, but with Sherri Shepherd as Jordan's wife, Angie, along with her very own Bravo reality show camera crew for Queen of Jordan. Nobody was safe from the spotlight! Here's the satirical opening.

While Simon Pegg and Nick Frost can certainly take on zombies, murderers, and aliens, George Lucas is an entirely different story. Watch as they try to recreate Star Wars—but immediately dissolve into bickering over Frost's R2D2 beeps.

What happens when you mix the Starcraft 2 trailer with an episode of My Little Pony? A tale of death, revenge and rainbows!

It's becoming increasingly apparent that Mummar Gadaffi and Charlie Sheen share the same strain of crazy. In this brilliant FOD mash up, watch the undeniably insane Libyan leader spout Sheenisms and still sound like ...himself.

Those who were fortunate enough to miss the muddled snoozefest that was Charlie Sheen's Ustream webcast tonight already have a better option: Duh! Winning!, aka SNL's version of a Sheen talk show. Look, it's Miley Cyrus as Lindsay Lohan!

On tonight's Late Night—the show's second anniversary—Jimmy Fallon was busy! Not only did Fallon slow-jam the news with Brian Williams, but he also impersonated Charlie Sheen—brilliantly, to boot—in this ad for Sheen's new fragrance, "Winning." Tiger blood!
