I am a member of Raindance (mostly because it gets me a discount on their classes, equipment rental, duplication, etc). Raindance also run a film festival in England each year, and this morning the founder was showing us a few of the adverts he has produced to advertise the festival over the years. A couple never got shown in public. One because it got an 18 certificate and the movie theatres were not keen on showing it. The other got banned outright by the advertising regulation authority. Here is the banned one, it made me laugh, but perhaps I have a sick sense of humour.
