Alright... I noticed this the moment I saw the Baseball episode for SC.
If any of you have seen both anime versions of these series you probably noticed it as well.
In the Gantz anime, everytime a Gantzer died they would show the Gantz ball, fade it to black and white and play a high pitched "ting" sound.
Samurai Champloo baseball episode they did the exact same thing except they would just pan in, create a frame, BnW it and do the ting sound. Funniest episode in Samurai Champloo imo. Great stuff.
Anyone else notice?
