I've only one, and it didn't even work for more than about 30 seconds.
But, over the summer, I'd been chatting to this absurdly cute girl that works at a restaurant in town. She kept teasing me about the fact that I hadn't seen the latest Dark Knight film, and refused to go have a drink with me until I did.
Eventually, instead of going to see it, I just said I did, and when she asked me about it, I inserted characters from the movie into the plot of Cool Runnings.
Never got that drink.
