Gotta thank urban_bohemian for turning me onto The Mischievious Boys!
They're 4 Asian guys who do online videoes lip synching to club songs (like Madonna's "Hung Up").
Oh, did I mention they're hot and shirtless? :D
Here's a few links:
The Mischievious Boys website (hasn't been working for me - maybe they're being innundated with hits!)
The "Hung Up" video
The rest of their videoes through Google video search
