Orphans and "Daddy"

Okay, listen up, you chucklehead. You, David Grimes, are not a smart bear. So, here's the lowdown: the joke plays on the double meaning of the word 'daddy.' On one hand, it refers to a father figure, which is something orphans lack. On the other hand, in some gay communities, 'daddy' is a slang term for a hot older man. See? The joke implies that gay people need a 'daddy,' and orphans can't have one of those. It's not great humor, but it might get a pity laugh from people who also have zero brains.
