Jamal: Dads CAN grow on trees, Joseph.
Joseph: No, they don't.
Jamal: Yes, they do. I've seen it.
Joseph: ... that's not what you thought it was.

Alright, listen up, numbskull. The joke here is that Jamal thinks "dads grow on trees" because he probably saw a tree that said "Dad" on it, but he is too stupid to understand what is going on. It plays on the naivety of someone who takes things literally. Also, because you read this I now know that you also are a nerd. Sad!
