Wild Card

[The Joker]

A little boy walks in on his parents having sex and says, “Oh no! What are you doing?”

His father tells him, “We're playing cards and your mother is my wild card.”

A week after that he walks in on his father masturbating. He says, “Oh my goodness! What are you doing?”

His father says, “I'm playing cards.”

“Where's your wild card?” the boy asks.

His father replies, “Son, you don't need one when you've got a good hand.”
