The Deadbeat's Happiness

Hey, listen up, buttercup. So, a deadbeat dad is a dad who doesn't take care of his responsibilities, like paying child support or being there for his kids. The joke is that the dad is so neglectful that he can't even be bothered to answer a simple question about what makes him happy. It's funny because it highlights how absent and uncaring he is. You probably know someone like that, because you seem to be having a little trouble keeping up.
