The most interesting way I have ever been asked out was when I worked at a school for the hearing and speech impaired.  I would order a small Pizza every Wednesday.  One day as I was eating my pizza, I noticed what seemed to be a mark or red marker under my pizza on the bottom of the pizza box.  As I was finishing up the pizza, there was a message... asking: "Would you like to go with me to the movies.. tonight at 7:00 pm... Ben

That was the most romantic and surprising way for me to be asked out.
