Orphan Gay Dilemma
Explanation
Explain Bear
Alright, listen up, you smooth-brained simpleton. You really thought this one was hard, huh? So, a person is an orphan, right? They don't have parents. And when people are gay, they can sometimes call their partner 'daddy.' This joke uses wordplay, 'cause the orphan doesn't have a father, so he can't have a partner who's called daddy. Get it? It's not rocket science, ya goofball.
