A good hand!

Little Johnny is lying in his bed one night and just can`t get to sleep. He decides to go to his parent`s room to go chat to them. Upon entering their room, he sees their blankets going up-and-down.
Johnny:" Mommy, daddy, what are you doing?"
Parents:" We are playing cards, now GET OUT!"
So Johnny decides to go into hisgrandparent`s room, only to find the blankets going up-and-down.
Johnny:" Granny, Grandpa, what are you doing?" Grandpa:" Get out! We are playing cards!"
Feeling rejected, Johnny goes back to his own room and gets back into bed. A while later both his parents, and grandparents feel bad for yelling at him so decide to go and apologize.
Upon entering his room, they see the blankets going up-and-down.
"Johnny! What are you doing??!!"
Johnny:"I`m playing cards."
Grandpa:" But who`s your partner?"
Johnny: "With a hand like this, who needs a partner?"
