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!
The movie was originally
shot on 8mm in 1971, and we recently digitized it. It's only about 7 minutes
long, but very funny. I can't seem to link to it here, but go to Google Videos and search for "TPing" ...
