I forgot to mention - when I was in town doing my Christmas shopping I purchased The Big Issue (please do the same - too many miserable buggers walk past and won't cough up a couple of quid) and as I did the guy said to me - honest to god - "Great. Cheers mate. That's me last one - I can go home now".
Mate - you really need to sort out your sales pitch.
EDITED TO ADD: Thank you for your comments but no I didn't see Jimmy Carr doing this gag. This is not a gag. It actually happened. He's the Big Issue seller with the long hair who has a dog who usually stands outside Waterstones in Birmingham just down from the Bull Ring.
