nothing actually properly bad. Whats your greatest achievement?
When I was about 17/18 at Reading Festival, me and some friends truely stuck it to the man (read: carling) by using this foolproof tactic at the bar -

you (me): Hi can i get 3 pints please?
barmaid: Thanks that'll be one million pounds / tokens please.
you (me): oh also can I get a cider please?
*barmaid turns round*
you (I) run away with pints. by the time they realise you are miles away from crowd. without handing them anything. Joy.

I think they've changed it so you pay upfront now. Those swines.

Whats your greatest steal to date?
Note: if your a policeman, this didnt happen.
Note: I wouldn't actually ever steal anything proper.

Thanks.
