Sports / games that should be in the London Olympics

Plenty of viable and popular sports are recklessly omitted from the Olympic games and below is an extensive list of sports and competitions which need to be included in the next Olympic games.

Chicken
A two-person team competes against another two-person team in a swimming pool with one person in the water and the other on their teammate's shoulders, wrestling the competitor off of the other team's shoulders. The best of three bouts results in the winning team moving on to the next round of competition.

Dodgeball
It worked in a movie so why can't it work in the Olympics?

Kickball
This summertime sport is hugely popular in park and rec leagues across America so why can't it move on to the next level? It's far more accessible than non-sports like Dressage.

Trench
An aggressive sport pitting two teams against each other, dodging balls from the opposing team and working together to free their captured team members from the opposition's trench. A lot like dodgeball but with more of a battle lean to it.

Floor hockey
Again, a more accessible version of traditional ice hockey. To make it more interesting it could be played on asphalt to increase the rate of cuts, scrapes and abrasions.

Tag
It's self explanatory and it would bring a sense of childhood whimsy to the Olympics.

That's all I can think of for now but what Olympic games or sports would you include in Olympic competition if you had control? Would you add more extreme competitions or include some kick-ass playground favorites?
