According to Wikipedia, the Gotthard Base Tunnel is the deepest rail tunnel in the world. So is the Seikan Tunnel. And look, the lead section on Istanbul states that the Marmaray rail tunnel is really the deepest. Let's flip a coin!
Talking about Istanbul, here's a well-sourced list of cities spanning more than one continent.
Let's stay in Turkey. For almost two years, Trabzon had more than one million inhabitants. Someone had his priorities straight and correctly formatted the figure, and when an IP-editor *vandalised* the article, he was quickly reverted. Job well done!
Trabzon's local football team 1461 Trabzon play their home matches in the Hüseyin Avni Aker stadium, at least that's what the article's first paragraph says. The infobox, however, thinks its the Akçaabat Fatih stadium. Maybe they switch stadiums at halftime?
Football-related articles always contain mistakes, but after several months, I found one ~~without a single mistake~~! Oh well, nevermind.

Never add content without citing its source.
Use for fun, but never assume Wikipedia is accurate on something - it probably isn't.
Talkpages are like Facebook, but for people with no social life.
