Ha! I've got a friend who, on his very early 20s, wanted to stay for a while in Ireland to learn English while working (Madrid, Spain, here). He had a big farewell party, drank a bit too much, and missed his flight early in the morning, only to find that he had booked a flight to BERLIN instead of DUBLIN.

He was so lucky to miss it, imagine that hangover-y arrival to Berlin imagining it's Ireland.
