To cover a house, or the nearby bushes & trees, with toilet paper, just as a practicle joke.
I used to TP when I was young, and in fact ended up
making a movie about it! As a high school english project, we were to get together in groups and
make a movie (we'd been studying filmmaking). Well, our group decided to tackle a subject we knew well - TPing! The result was "The Art of TPing, or How to Gift Wrap a House," which received an A-. The minus was for a crude little joke in the movie, which
you will see if you view the movie, now on Google Videos!
