I Would, Except I Don't Have Change for a Hundred

My son came up and asked:

"Daddy, can I have eighty dollars?"

- "What do you need eighty dollars for?"
I asked.

"I need to buy a light saber."

- "Oh."
I said.
"Where are you going to buy a light saber?"

"At the Dollar Store."

- "Oh."
I said.
"So you should be able to afford a backup as well."
