Black and Blue Berry

I've created a new game. I call it "Berry-Blocker".

How you play is you just walk down a city street. Preferably in the tech or biz section of town. As you walk down the street, look for people who have their focus buried in a Blackberry. Thumbs nervously tapping the tiny keyboard. Flicking the centre nub or thumbing the wheel trying to read the latest emails. Brow furrowed as they concentrate all of their vision on a small, tiny screen.

Now walk toward them normally; don't run. Just walk. They'll walk directly towards you, not paying any sort of proper attention. When they're in range, just stand still. Don't do anything.

If you time it right, they'll walk directly into you. BANG! (You must be at least three paces away from the person. Any closer and it's a fault)

"What did you just do?", you will ask.
Apologies will be offered.

Score 10 points. Plus 3 more if they get agitated and angry that you let them walk directly into you.

First player to 50 points wins a free Grande Mocha Frappé Papier Mache Latté from the other player(s).

Now go play in traffic!
