"Severe or persistent sore throat or sore throat accompanied by
a high fever, headache, nausea and vomiting may be serious. A
slight tingling sensation in the back of the skull is normal, but
the desire to continuously chant `Py-co-pay Softex' should be
strictly avoided. If you find yourself sucking on your toes in
public, if you suddenly rip out your own appendix for no particular
reason, or if you die, consult a physician immediately."
