Finn's First (Funny) Joke

Finn's been telling jokes since he could talk.  Unfortunately, they're terrible.  His timing is bad and he doesn't seem to understand the concept of a punchline.

An example:
"Knock, knock"
"Who's there?"
"Poofy"
"Poofy who?"
"Bloofy!  HAHAHAHAHAHAHA!"

Etc.

So it is with great pleasure that I present his first structured and entertaining joke.  The delivery is still rushed and it's followed by some weird little punchline dance, but it's progress!

For those having trouble deciphering this brilliance, here's a transcript:
"What do you call a deer with no eyes?"
"I don't know, what?"
"I have no idear!"
[No transcript available for what follows the punchline.  You'll need to fill those blanks in yourself.]
