"Hidden" joke

Little johnny was going to school.
Incredibly he found a genie and was given 3 wishes.
"Can I have a piece of candy?" he said.
"Kid, I am a powerful genie ask for something else."
"Mmmm, ok, give me 2 pieces of candy."
"You think I have time for such small wishes? Don't ask for something so small."
"I want candy."
"Ok kid here you go; infinite candy."
"Cool, thank you."
"Ok whats your second wish? Kid, i don't have all day."
"But I still have 3 wishes.."
