Replying to Who do you want to fight?

Sometimes the only way to solve a problem is good 'ole physical violence.  Who would you like to fight??

The choices are endless, they could be...someone famous, an athlete, a place, your friend, a made up character, an inanimate object, an idea or abstract thought, someone on NS (bonus points if it goes down, but as always, pics or it didn't happen) etc...  Don't limit yourself to people, sometimes a verb or adjective needs a good ass-kicking too.
