Why Did The Tester Cross The Road ?

Currently working in London, I walk from the mainline train station rather than cram into the hot stuffy sardine tins called The Tube. Only problem with this is the pavements are crammed with tourists taking pictures, studying maps and buying tacky souvenirs.

The way round them is to walk in the road, hopping back onto the pavement when I see a homicidal black taxi steering towards me.

Works fine apart from at the main pedestrian crossing points. The road has big white LOOK RIGHT instructions so the pedestrians dutidully do that - and dont notice the commuter barelling down from the left wanting to get home.

Well, some pedestrians do notice - they are the ones with the tester mentality who know to expect the unexpected and not to blindly follow the manual.

I didn't come up with a punchline to the title of this post - any good suggestions then let me know.

What I did find and I dont know whether to be amused or scared by it is that the TSA ask and answer the question about chickens crossing roads and come up with the answer "because it's a terrorist plot"...
