A son ask his dad to explain the difference between reality and fiction.

Dad: It's complicated but let me try to explain. Honey, would you sleep with the neighbor for 100,000$?

Mom: Yes of course because I know we need the money.

Dad: Very good. Alright now Tasha, would you have sex with the neighbor's son for 200,000$?

Daughter: Yeah sure!

Dad: Perfect. So you see son, right now we would have 300,000 fictional dollars but in reality we have two whores in this house.
