It may be April Fool's Day, but by all accounts, this video is real. The master of transparency, Julian Assange, must have discovered that turnabout is fair play when this video of him dancing at an Iceland club was leaked to the 'net. This guy knows how to get down!

In the latest installment of "Snappy Answers to Silly Questions," Barack Obama explains to the Univision anchor that not only does he have an iPad, but he has, in fact, his own computer. No, the President of the United States of America doesn't have to borrow somebody else's computer to check his e-mail.

If you've got a fear of heights, it's probably best to stop reading now. You definitely won't want to watch this video of Alain Robert, who's made a name for himself scaling skyscrapers around the world, climbing the Burj Khalifa, the world's tallest building. 828m up, he manages a smile — I think most people would've just fainted.

Rooster Teeth, the noted machinima studio behind the long-running series Red vs. Blue, have decided to add some action to a game much more casual than their usual fare. They've made an impressive live action trailer for "Angry Birds," convincingly importing a collection of action and military movie cliches into the mechanics of the game. "Angry Birds" fans are out in force for it too, racking up millions of views in the few days since its posting.

With any luck, this is the last video about that stupid Rebecca Black song that's ever worth posting. But yesterday was Thursday, tomorrow is Saturday, and this video is too funny not to spread through the world. Here's "Friday," the song we all know and love, as interpreted (and then re-recorded) by bad lip readers. With the power of the subtitled suggestion, it really looks like she's singing these lyrics which, at times, are more ridiculous that the original.

It must be difficult to speak on live television today. All of the anxieties of speaking in front of a large and unseeable audience, multiplied by the knowledge that whatever you do will be preserved forever on sites like YouTube. That's exactly what happened to this Toronto reporter, who must be new to the teleprompter. One can only imagine how scary these 15 seconds were for him.

Sure, the title should be shortened to "Don't steal computers," because it's almost always a bad idea to do that. But then, it's a really bad idea to steal a computer from somebody who is a famous developer, and then an even worse idea to record videos of you dancing on that computer. That's what the thief shown in this video did, and when the developer recovered the files (remotely, of course) he posted them to YouTube to maximize the embarrassment of the thief. The thief has since returned the laptop, and asked for the video to be taken down, but according to the owner, he's in no position to negotiate.

Disney's got a special power over people. For generations, their films have defined what a children's movie should be, and the songs and words have been internalized by millions of children. Nick Pitera, an animator at Pixar, must have been one such child, and his "One Man Disney Movie" is an impressive testament to that fact. Nick sings six different roles, each one comprising a handful of characters, in a well choreographed and neatly presented package.

Kutiman, the YouTube remixing superstar behind Thru-You two years ago, is at it again. He's come out with a new YouTube remix video called "My Favorite Color" that digs even deeper into the YouTube deep cuts for source material.

On the Friday of a week where the viral videosphere was dominated by a song called, incidentally, "Friday," how can we think about anything else? This cover by Matt Mulholland ensures that we cannot. While the original was lambasted for the lack of emotion on the part of the singer, this dark twist will take no such criticism.

Even the lowliest form of cinematic art — the "superhero movie" — can be redeemed by a good, dark origin story. "The Dark Knight" was considered for Best Picture nominations, and "Casino Royale," which gave Bond fans a look into the hero's sad past, was considered the best 007 film in years. This week in Austin, the South by Southwest film festival is happening, and in a promotional move, a team of film makers decided to imagine Mario, the protagonist of so many Nintendo games, getting the same treatment.

As so often happens on the internet, last week saw an unusual piece of media — in this case a bizarrely bad teen pop single called "Friday" by previously unknown Rebecca Black — absolutely explode in popularity. The auto-tune, the inane text, the blank expression on the performers' faces, all conspired to make this one a hit. And so the parodies started coming. There have been plenty of covers and responses, but none has been so pitch perfect as this video, which suggests that the song was actually originally performed by Bob Dylan.

The creator of this video will need to produce a bit more documentation before the internet crowd stops calling fake, but it appears to documents a team of two overriding the video screens in Times Square with images beamed directly from an iPhone. This is either some seriously impressive hacking — unlikely — or some handy camerawork and post production. In either case, it's worth watching!

It's no secret that most of the movies coming out of Hollywood these days are pretty derivative: prequels, sequels, adaptations, remakes, re-imaginings, and spin-offs abound. So why not just use the footage itself from an earlier movie? This recut trailer imagines the 1980s classic "Ferris Bueller's Day Off" as a contemporary coming-of-age film, and uses only footage from the original to make that real. It's not a real movie, but it already seems better than much of what's coming out this year!

Sure, there's no higher purpose to it, but sometimes things are so cool you just have to do it. In this video, a team of awesome people made a full-scale shell of a house and attached hundreds of helium balloons to the top. Amazingly, they achieve liftoff, and create a real life version of the house from "Up," taking to the sky on balloon power. Heartwarming!
