I worked for that company for almost 3 years. They used to have a guy that you could bring in for special events that would shoot up fruits and veggies. The deal was that you had to take the guy shopping at a grocery store and help him purchase like $500 of misc fruits and veggies. He would shoot all kinds of melons and heads of lettuce, etc..
It was a little different but that kind of stuff did get a crowd excited.
