I was watchin episode 3 and I noticed for a few seconds that there was a figure in the background that had the face and the look of Jin from Samurai Champloo. I was like "what the heck?", but the glasses, the face, the look, the hair...all of them looked exactly like Jin.

It could be that the guy who makes The Boondocks also likes Samurai Champloo because Samurai Champloo deals alot with hip hop culture.

yea i saw that too it was werid but iwas also like cool ya know because samuri champloo rocks

Yeah I saw that as well
