I remember that. If they had of lived up to the intro it would have been a really good show. So many comments have said they wish Nick would go full on Grimm.
One of the most self-aware things the show has ever done was get rid of that awful intro. It was absolutely pathetic! Grimm's into is just fine without words. Listening to that made me glad that Sanford and Son never tried to add lyrics to their intro.
