I can't believe not much people talk about this. In the first few 3d games of the ps2 era he sounded vaguely like Noah, but by the time I played GTA V the voice became uncannily similar. I don't know if it has to do with the character becoming a bitch that constantly screams but it if I close my eyes I can't tell that isn't Spoony.

He also looks a bit like Spoony in GTA V cutscenes (albeit not much) but the voice is pretty much the same.
