Nobody's Perfect

I am reminded by one of the comments on the Pissups and Breweries thread below of the time when a tyre fitter came to give evidence in support of a tipper-lorry driver who had been done for a defective tyre.

The fitter was an engaging chap, and he meant well, but his evidence was pretty hopeless. The prosecutor, in cross-examination, pointed out that the witness had completely contradicted something that he had said earlier. "Well, I made a mistake, didn't I?" came the reply. "People make mistakes. That's why they put rubbers on pencils, innit?."
