What prompts the narrator to recall his college days?

The narrator is in his apartment, drinking. He says to call him Dave, but that is not his real name. Beneath his window, picketers are protesting, and the narrator throws down a paper airplane with a note from God, claiming that he's coming to get them all. He's flipping through the television channels, and only escapes the news of the strike by watching PBS. The guest speaker happens to be a man the narrator knows from college, now a professor, named Umbaugh. Umbaugh is discussing the results of boredom. The narrator casts his mind back to his college days.
