Cele mai ciudate acorduri de înfrățire între orașe. Pe listă sunt localități din România, orașe fictive și jocuri de cuvinte

City twinning often involves unusual partnerships, including fictional cities and humorous connections. Examples include Dull, Boring, and Bland, which have seen tourism boost due to their quirky names. Other notable twinnings include Berwick-upon-Tweed and Sevastopol, stemming from a historical error, and Wincanton's official bond with the fictional Ankh-Morpork. Romanian cities also engage in twinning, though many agreements remain largely symbolic. Modern city twinning emerged post-World War II to foster peace, with Coventry and Stalingrad as early examples. However, political tensions can lead to the dissolution of these ties, as seen with various UK councils severing links with Russian cities after the Ukraine invasion.
