My mom was trying to get her GED in the 90's. She failed, but I found one of her essays in the storage shed once. It was about how 1-900 numbers are bad for society because her nephew ran up a $200 phone bill using one.

It was hilarious. For those of you who are too young to remember, 1-900 phone numbers (at least in the USA) used to be pay-per-minute sex lines. I think there were some joke lines and other things too, but it was mostly phone sex.
