MEGAPHONE CROONING

I just thought of the megaphone crooning sketch from "Mr. Show" out of nowhere and started laughing out loud. Here are funny things I remember from the sketch. I did not just watch it, this is off the top of my head.
  1. "Thank you."
  2. The fact that audiences liked David Cross' character because he was polite.
  3. The audience booing at "electric sports bra" because it was a bad invention.
  4. The sketch ending with Bob and David as old men in the movie theatre.
  5. The line the goes something like, "We used to call it Megaphone Crooning, otherwise known as Megaphone Crooning."
  6. "Racking up electric ties!"
  7. Does anyone know who wrote the Megaphone Crooning sketch?
