Loan from Jonny

Little Johnny was being questioned by the teacher during an arithmetic
lesson. "If you had ten dollars," said the teacher, "and I asked you for
a loan of eight dollars, how much would you have left?"
"Ten," Little Johnny answered firmly.
"Ten?" she said, "How do you make it ten?"
Replied Little Johnny, "You may ask for a loan of $8 dollars but that doesn't mean you'll get it!"
