The teacher asks little Johnny if he knows his numbers. 

"Yes," he says, " I do. My father taught me." 

"Good. What comes after three?" 

"Four," answers little Johnny. 

"What comes after six?" 

"Seven." answers little Johnny. 

"Very good," says the teacher. 
" Your dad did a good job. What comes after ten?" 
  

Little Johnny smiles and says, " A Jack then A Queen."
