My late cat once threw me into a world war in Civ. This happened when the game currently had control over one of my units, and he tapped the 3 button on the keypad, and his pressure from the paw pressed on the boardm, so he hit Enter a half-second later. The unit jumped across the border and attacked a Russian unit to the southeast. Then, all the defense pacts kicked in and I was at war with everyone.
After a valient final stand at my capital, I was conquered 63 turns later.
To imagine, World War I was started when a Russian soldier was assassinated by a gray cat named Mita.
