Feargus O’Sullivan wrote about Bucharest and Budapest’s attempts to stop being confused for one another:

• Michael Jackson, Iron Maiden, and Metallica have all gone on stage in Bucharest – Romania’s capital – to yell “how are you doing, Budapest” – the capital of Hungary.
• A campaign has recently been launched to end the confusion. At Budapest airport for example visitors see a “Welcome to Not Bucharest” sign.
• The confusion is particularly irksome since political relations between Budapest and Bucharest are often tense.
