A few weeks ago in Budapest:
Matthew: Dad, How much does a 4 ct box of cicken nuggets cost at McD?
Me: HUF 230 and that includes the sauce.
Matthew: And how much does a 6 ct cost?
Me: HUF 620 with the sauce.
(About two minutes later.)
Matthew: So I can get 6 pieces and a sauce for HUF 620 or 12 pieces with 3 sauces for 690?
Matthew: So how stupid do you have to be to buy the 6 piece one?
