It might just be me stretching in my search for some redeeming quality in the most recent South Park episode, but I think Dopefish may have made an appearance:

It may not be intentionally Dopefishesque though, since there is no sign of the characteristic protruding teeth. If my cable reception was better it might be more determinate...
