Montemagno poses a short puzzle: a hat and a pen cost €1.10 together, and the hat costs one euro more than the pen. He asks for the price of the pen and presents the problem as an invitation to pause and reflect rather than answer instinctively. He does not give the solution in the episode.

Key points

• The puzzle combines a total price and a difference between two objects.
• The aim is to slow down an automatic answer; the solution is not explained.
