The boardroom is full today because the company’s former Chairman, Mr. Ralph Finley, is in attendance to make a special endowment to the R&D group, among others. Twenty people sit around the rectangular conference table, all waiting for Mr. Finley, who is having a coughing fit. In between blowing his nose, he mutters to them, “Allergies, I forgot to take something for them today.” The people murmur their understanding. Suddenly, Mr. Finley sneezes so hard, his dentures fly out of his mouth and clatter on the table. For a moment, no one seems to breathe; the only sound is the clacking of teeth.
