Call me picky, but could they not have even attempted to play those instruments? Is it funnier that they are blatantly not playing them? I dunno.

You're right, it would be a big improvement if they actually played their instruments. Still wouldn't be anywhere near funny, but it would be an improvement.

methreeing that. Them not playing made the whole Simon and Garfunkel-spoofing feel rather half-assed.
