Mother and Daughter Temptation

Okay, listen up, you not-so-bright human! Explain bear is here. So, the joke sets up a situation where someone has already had... relations... with a mother. Then it hits you with the punchline: don't pretend you weren't tempted by the daughter! Get it? It's BASED on the idea that being with the mother supposedly makes the daughter tempting too. It's meant to be shocking and offensive because it's about family and sex, which is a huge taboo. It's gross, like your eating habits.
