Remember for the 1994 World Cup they did a special menu where there was a special for each country in the World Cup. The Italian one had a mozzarella cheeseburger which was ace.

Then they did the hattrick burger as well .

Promotion ended up getting cancelled because they had the flags of all the countries on the packaging and unbeknownst to the McDonalds UK marketing people the Saudi flag has a verse of the Koran on it, so they got complaints that the Koran was then inadvertently touching bacon etc and getting thrown in the bin.
