Grandmas don't know everything....

  Little Ralph was 7 years old and was staying with his grandmother for a few days.   
He'd been playing outside with the other kids for a while when he came into the house and asked her: 
"Grandma, what's that called when two people sleep in the same room and one is on top of the other?" 
   She was a little taken aback, but she decided to tell him the truth.  

 
 

It's  called sex, darling." 
   

Little Ralph  said, "Oh, ok," 
and went back outside to play with the other kids.   
   

A few minutes later he came back in and said angrily,   
"Grandma, it isn't called  sex.   
 It's called Bunk Beds.   
 And Howie's mom wants to talk to  you."
