We realize there's only so much time one can spend in a day watching new trailers, viral video clips, and shaky cell phone footage of people arguing on live television. This is why every afternoon The Atlantic Wire highlights the day's video clips that truly earn your five minutes (or less) of attention. Today:

Before he was America's most trusted fake newsman, Jon Stewart was just another floppy-haired, easy-fit jean wearing mid-1990s cable variety show host. Which is why the 1994 highlight reel from The Jon Stewart Show isn't just a smashup of alarmingly broad sketch comedy and men wearing oversized earth tone button-down shirts unbuttoned over tucked in tshirts: it is 1994, both the good and the bad. Stewart's grown up, settled on a hair style, and put away childish things, like live performances from The Cranberries and curling up like a baby in guest Ned Beatty's lap. That's a loss, but probably not a crushing one. You can sort of see why they made all those mean jokes about this show when Stewart had his arc on The Larry Sanders Show.  [Vulture]

Rick Perry's tried to hit Mitt Romney with a snappy canned attack line in Thursday's GOP debate, but ended up sounding like a character out of a Faulkner novel, or maybe just Miss Teen South Carolina 2007 Catie Upton. We need to see them both in an Oxford-style debate before we can say for sure. [YouTube]

Scientists at the University of California-Berkeley have used an fMRI machine and computer models to render the brain waves from three research subjects as fuzzy, wavy video clips. The signals were recorded while the subjects watched movie trailers and the result is so fascinating, you won't even yell "FOCUS!" at the guy in your mind's projection room. [Idea Lab]

Few things on television are as pleasing as David Letterman conduct an interview that veers off the rails into surrealism. That's where his segment with Modern Family's Sofia Vegara ended up last night. Things progress swimmingly until Vegara said the Emmys are not, in fact, a beauty pageant. [CBS]
