You may already know of Jake Byrd. The goofy gatecrasher and Jimmy Kimmel Live regular has been spotted everywhere from Motley Crue's Hollywood Star Ceremony to Paris Hilton's release. But those who didn't already know him got a big dose this week at a press conference by Yale Galanter, OJ Simpson's attorney.

Wearing an "OJ 07" T-Shirt and an "I *Heart* Famous People" hat, Byrd interrupts Gelanter to congratulate him and offer him a high five. He continues to chime in with words of support, stopping only to resort to theatrical facial expressions in the background or -- once -- take a call on his cell phone.

Who is this guy?

Jake Byrd is the alter ego of comedian Anthony Barbieri. He first started fooling fans and major news outlets when he popped up as a "super-fan" during the Michael Jackson trial, managing to convince both the New York Times and Court TV of his legitimacy. His Kimmel segments are titled "Jake Byrd: Celebrity Avenger."

I don't know if all the celebrities Byrd avenges are grateful, but Galanter, at least, seems to appreciate the support. So when's Galanter gonna thank TDR for our High Five?

Overearnest celebrity PSAs are certainly not new or rare things. You can't get through a commercial break these days without some marginally famous person telling you the planet is dying, or reading is FUNdamental, or hey, it's okay to be gay. All of them seem sincere, and most of them are probably worthwhile. But few are as deeply moving as this one. And it's from Jim Carrey, of all people.

Sure, it may take a second for the more cynical among us to get past Carrey's Jesus hair and his intense, "NO SERIOUSLY, GUYS, I'M BEING SERIOUS" face. But give the funnyman his due: when he's talking about Burma, about the abuses its military regime has heaped on the people, and the brutal and tragic imprisonment of Nobel Peace Prize Recipient Aung San Suu Kyi, his message is anything but amusing.

Even the most aware of us can sometimes forget just how much is going on outside of our little corner of the world. Hopefully, Aung San Suu Kyi will not have to be imprisoned for another eleven years before the world starts paying attention to her and the Burmese people.

Just when you think Christopher Walken can't get any cooler, he does. Seriously, is there a more awesome guy in all popular culture? The best thing about him is that he loves imitating himself almost as much as everyone loves imitating him. You know that film geek book series that boasts titles like Scorsese on Scorsese and Cassavetes on Cassavetes? With this guy, it's more like Walken on Walken on Walken.

This clip was submitted by Walken to the Web site Im Cooked. And it features the man himself preparing a delicious dish of baked chicken and pears. All this meal needs is -- that's right -- more cowbell.

Last week, music mogul/rapper/clothing designer/nouveau-Gatsby P. Diddy put out the call for a new assistant, encouraging anyone who thought they had the right stuff to make their case in three minutes or less, and upload their "video interview" to his group on YouTube. 10,000 application videos later, an exhausted-looking Diddy's back with an update and a bit of clarification on what he's looking for.

Listen up, kids: If you want to assist Diddy -- a job which involves everything from getting him ready for the red carpet to aiding in billion dollar deals to helping him jump out of planes in movies -- you need to actually be able to do a few things. You need to be able to read, write, and count, for instance. (I'd think Diddy was being facetious, but just the number of videos that run well over three minutes is evidence enough that he's right to put his foot down on the counting issue.) You also need a college degree. Geez. What is this, a real job?

The full slate of videos can be found here. Presentation styles range from the zany to the down to earth, but if you plan on watching them all ... you'll probably need to hire an assistant.
