Embarrassing fact: during this world cup, Portugal and Congo were playing a match. The letters were POR-COD.

There was a moment when the result was 1-0 so it was POR-COD 1-0. Also readable as PORCODIO, something that in italy is considered blasphemy. So, to avoid this exact situation, they changed the graphic in Italy to PRT-CNG. I wish I was kidding.
