I am not encouraging you to write bad ad copy, but have some fun. I got a great response when I turned the photo of myself on my website upside down. Why? becauise it was different and people noticed the change and purchased the product.
The main thing is to get the buyers attention, not an easy feat these days.
Here are some fun ad titles:
Mrs Browns Jam gains a Cosmic audience
Pope Francis sells his donkey
These tires will last 5 miles - fantastic value
Have some fun and break out of the mould.
