@thedonz5 season 9 episode 172. This is the http://TV.com  link to the episode in question as far as i can tell: http://www.tv.com/shows/late-show-with-david-letterman/show-1827-170441/ … Thank you so much in advance!!

Yeah, that's the June 19, 2002, show.

Since i imagine the episode is obscure- just because there are so many... I don't know if you would remember, but was the high-schooler good? Once again, i can't thank you enough for some validation that this exists somewhere! I spent a week online last year with nothing to show.

What do you recall that prompts you (and others?) to search for this particular one?

The creator of a TV show named gravity falls Alex Hirsch was featured on that episode. What sparked me to start looking again and how i found you was that someone on reddit suggested contacting you. He won't do bird calls at all anymore so everyone is curious.
