A traffic cop is on his way back to the station at the end of a shift when he happens to find himself behind a particularly good driver. This guy is doing 28mph on the dot, his mirror,signal,manoeuvre was was text book perfection, he followed the 2 second rule exactly and never made a single mistake for 8 miles. When the guy stopped at a newsagents the copper got out to congratulate him.
"I must say sir that i have been behind you for nearly 10 miles and your driving has been nothing short of superb.I have spent the whole shift stopping idiot drivers so its a joy to witness such skill behind the wheel,well done sir."
"Thanks very much" says the bloke,"well you've got to be a bit carefull when you've had a few!!!!!!!!!!
