This is my fave one from Wonderland at the moment: what is a "substantial meal"?

This Housing Minister says that if a pub served a pasty and beer this may get them into trouble, but explains that if they serve the pasty with a lettuce leaf this is a "normal meal".
He then cheerily announces that this should "clear things up!"
With rules as definite as this, publicans will need a very long list indeed..
Well, at least after you have ordered one "normal meal" you can sit in the pub all afternoon and evening getting pissed....
