Those boys over at Funny or Die are up to no good once again, and this time they've created a video called High-Five Hollywood (see above). Featuring folks like Will Ferrell, Mary Steenburgen, Ryan Seacrest, Milo Ventimiglia, Tim Meadows and Blake Lewis, the video follows a couple of guys who run around Hollywood high-fiving each other ... and then turning to look into the camera. I don't know why this is funny, but for some reason I'm still laughing -- and I watched it over an hour ago. If you're from Los Angeles (or at least familiar with the city), you'll notice tons of hot spots ... with the exception of the WGA picket line (would've liked to see some high-fiving over there). I take it from here on out, we'll see more videos of the boys high-fiving their way across the country. Check it out above, and let us know what you think.
