Now, some people do this for shock value. Shock is just another uptown word for surprise. Granted it has a different quality to it, but a joke is about surprising someone. I'm a great believer in context. You can joke about anything. I do like finding out where the line is drawn, deliberately crossing it and bringing some of them with me across the line, and having them be happy that I did.
George CarlinWhen something is 'new and improved', which is it? If it's new, then there has never been anything before it. If it's an improvement, then there must have been something before it.
