There was a fella who I used to go to Millwall with a few years back and he used to do exactly that. Not only that, but he spat when he talked. It was ****ing horrible. Since he has not been coming down for a while, I have saved **** loads on rain coats.
I must admit, I did try it with an ostrich once. Well, she was stood there, head in the sand, you know, and I thought why not. It was great for the first hundred metyres, then I got out of step.
