Ok I haven't seen Micro-Phonies in a few months, but isn't the quote:
Larry: Do you know Six Steps From Lucy?
Drunk Pianist: Know it? I wrote it!
I always thought that was what transcribed since that's one of my most-quoted lines. I'd hate to have it wrong if this is what it is (according to the site)...
Larry: Do you know Six Steps From Lucy?
Drunk Pianist: Play it? I wrote it!
Who's right.
