I've been spending a lot of time at YTMND.com lately, getting caught up on what has been going on there since my first visit. Of the thousands of pages there, I have to say my current favorite is Dr. Dre ft. Cosby. It's pure genius: clips of "Cosby" from episodes of The Simpsons and Family Guy set to the instrumental to Dr. Dre's "What's the Difference" (Dr. Dre 2001). Proceed directly there and have a listen.
