My memory is a little foggy so bear with me. I wanna say it was from around 2 years ago, it had those 2 (green & pink) vertical rectangular shaped guys from Aqua Teen Hunger Force & they were signing along with the theme. The only verses I recalled were "shake it up now" & "get down get down."
hmm... are you by any chance remembering the "Calling all Freaks, Playas, Pimps" song? I don't recall it being a bump, but if I recall correctly it ran during the credits of that episode and possibly a promo :?
You know what, I think it was used to promote an episode.
Go to this page: http://www.asfdotcom.net/download/athf.php scroll down about 3/4 of the page to the 'Rap-esque Promo'
Its not the exact one but still close enough
I give you props for your effort.
I don't know if I can track down the episode it's from, I'm guessing you're looking for the credits. :| I can't remember how much of it was performed during the ep itself.
it wasn't from the credits, it was just a little promo for a ATHF episode.
