Probably the most meta song lyrics ever!

This is the theme to Garry's Show,
The theme to Garry's show.
Garry called me up and asked if I would wright his theme song.
I'm almost halfway finished,
How do you like it so far,
How do you like the theme to Garry's Show.

This is the theme to Garry's Show,
The opening theme to Garry's show.
This is the music that you hear as you watch the credits.
We're almost to the part of where I start to whistle.
Then we'll watch "It's Garry Shandling's Show".

This was the theme to Garry Shandling's show.
