We discussed the importance of the public service announcement "Don't get hooked on legalized speed to fit in your jorts." Sometimes I fear that not everyone gets my sense of humor and will hurt themselves. Not everyone can be a massive drunk who runs marathons after two days of partying. (I really did run the Yonkers Marathon drunk but I don't recommend it.)
