(Grandpa) "Honey did you know that kids these days don't put their tooth under the pillow for the tooth fairy? What they do is take a digital image and upload it to the toothfairy website they then get paid in bit coins."
(Grandma) "Dear, you've been talking to your grandson again and he's pulling your leg."
(Grandpa) "Billy, why would you make up a story about the tooth fairy?"
(Grandson) "Let me get this straight... you make up a story about a fictitious character, you then tell it to my parents who perpetuate the hoax. I decided to elaborate on it and you're calling me out!"
