Little John woke up in the middle of the night to go to the toilet.
On the way back to bed, he passed his parents room. When he looked in, he noticed the covers bouncing.
He called to his dad, "Hey Dad, what are you doing?"
The dad answered "Playing cards"
Little John asked, "Who's your partner?"
The dad answered, "Your mam".
Little John then passed by his older sister's room. Again, he noticed the covers bouncing. He called to his sister, "Hey Sis, what are you doing?"
The sister answered, "Playing cards."
Little John asked, "Who's your partner?"
She answered, "My boyfriend, Paul."
A little later, the Dad got up to go to the toilet.
As he passed Little John's room, he noticed the covers bouncing. He called to his son, "Hey son, what are you doing?"
Little John answered, "Playing cards."
The Dad asked, "Really . . . . who's your partner?"
Little John answered "You don't need a partner if you have a good hand!"
