But you also can't just say, "that guy is using monopoly money, so therefore I have more money than he does because I really want that to be true."
Especially when the teller keeps shooting down all your claims (not to mention the bank manager, the board of trustees, and anyone else who takes five minutes to laugh off your claims that "thousands of people will claim that one time he played Candyland and therefore he only had monopoly money" and other nonsensical and easily rebutted junk arguments like that.
Fun analogy though.
