Suffolk police have a reputation for being witty. Here's an article about their latest efforts to encourage sensible behaviour around Christmas:
Suffolk police launched the list in a poster campaign that they say is designed to "ensure you have a night to remember rather than a night to forget".
It tells drinkers: "Things that are difficult to say when you're drunk a) Innovative b) Preliminary c) Cinnamon". It adds: "Things that are very difficult to say when you're drunk a) Specificity b) Passive-aggressive disorder c) Transubstantiate.
It then presents a list of "things that are absolutely impossible to say when you're drunk", including: "Good evening officer, isn't it lovely out tonight?", "I'm not interested in fighting you" and "Where is the nearest toilet? I can't possibly vomit in the street."
Try saying 'preliminary transubstantiation' a few times. Drink some wine and try it again. Or, hey, don't bother. In the interests of science I will test this theory for you. Stay tuned...
