I take that back. I realize the meaning of classic now.
And I did download the parody. I could tell it was an older clip (not 1980s old) as I saw the tail end of "Daddy Dear" upon playing the clip, and I do not remember hearing tell of "Daddy Dear" after 2000.
Maybe my comment about "not classic enough" is probably based on my preference for pre-1985 era Sesame. Maybe I'm just not a fan of post-1990 computer animation or something.
But the letter D Dragnet parody was pretty interesting, though.
