Some years ago when I was living in Illinois, I watched a lot of movies in the local theatres. At one point one of the local theatres was offering free admission just for bringing a comb.
Well, I had one of those huge novelty combs.
I couldn't resist.
When I got to the ticket counter, I pulled out my huge comb from under my pants leg. The line behind me promptly went to pieces...
I got my free movie. Good movie, it was.
