The shirt reads: “TRICK OR TREAT EXCHANGE RATE” — with an equation below: 1 BIG BAR = 4 MINI BARS.
The rate is set out properly, a full-size bar on the left and four wrapped miniatures on the right, with a small ghost sitting at a table beneath it holding up two fingers beside a pumpkin bucket.
Anyone who has sat on a living room floor on the first of November has negotiated this. The ghost appears to be running the desk. For families with more than one child, and for the parent who is quietly taking a commission.
