When I would buy a fairly expensive card I'd tell my dad "If you would have bought this same card when you were a kid it would have only cost you a penny plus you would have gotten a piece of gum, so technically it's your fault I had to pay this much because you weren't thinking ahead". He got me back by saying "I did buy baseball cards back then. I chewed the gum and then I put the card in my bicycle spokes to make motorcycle noises".
