The queer thing about this question is that Ren and Stimpy is the kind of cartoon Beavis and Butthead would've dreamt up. Well, that or Boogerman. Those three together would make a wonderful package to give some friend's young child for his first Genesis.

I'm going to have to bow towards B&B here. R&S has that 2P advantage but given the material I think it a bit of a waste.
Should've made a B&B on Sega CD: could've included their music video watching routines.
