Ok, This joke just fits:
A boy named Johnny walks in on his parents "doin it" one day and gasped at what he sees
"Daddy! What are you doing?" Johnny asks
Startled, the father replies, "Uhhhhh, I'm playing poker son" "Well, whats Mommy doing?" Johnny asks again. "Ummmmmmmm she's my wild card" replied the father. To both parents surprise, this was an acceptable answer to Johnny so he left them alone. After a few minutes the mother gets worried about what her son just saw and asks the husband to go talk to him. The husband obliged and headed into Johnnys room. When he opened the door, he was shocked!!! There was little Johnny "pleasing" himself.

"SON WHAT ARE YOU DOING!?" The father screamed. Johnny answers his father with, "I'm playing poker Dad" baffled, Johnnys dad goes, "Well, then wheres your wild card!?" Then, Johnny says, "You don't need a wild card when ya got a good hand!"
