I remember not knowing one, putting my marker at some random place on the map, and then, once I saw the answer, saying "Oh, a Portuguese city! No wonder I didn't know it!"

Then, in one of the later rounds, I got another one I didn't know, put the marker at a random spot on the map, and, when shown the answer, said "Not ANOTHER f*cking Portuguese city!"

Maybe it gave me the same one twice and I just have a really bad memory
