King of Undefended Cities
I can't say there is one civ that is always a pain in the butt. The Ottomans did sneak attack me 3 games in a row a while back.

In my current game (Romans, huge pangea, 3 million years), they had a few cavalry units in my territory (but the AI always does that, so I wasn't worried), and launched a sudden and devastating sneak attack, capturing a size 18 city guarded only by a EMPTY army, and destroying my military academy!
