A flight carrying the Auburn basketball team had to declare an emergency after a fight between player broke out while airborne.  One player was "bloodied."  The initial report was "roughhousing got out of hand." 

The message forums are hilarious saying it was the result of a three way love triangle where two of the players were hooking up with each and one got caught with another dude.  Whatever happened mist have been quite a brawl to declare an IFE and ask for police to be waiting when you land.

 

I've never heard of declaring an emergency asking for nearest landing then later changing your mind and saying we just want to go back home.
