The snopes article clearly says that it's bullshit:

If USC (University of Southern California) has had a philosophy professor on staff who for the past twenty years devoted a class period each semester to disproving the existence of God, it's news to them. "Professor Dallas Willard, who has been here for 32 years, affirms that nothing like this has happened during the time he was here," said USC philosophy professor Edwin McCann in 1999 when the e-mailed version of the tale was running rampant.
No one has named this professor or stated he was in class the day of the anti-God lecture. Call this current piece of netlore just an update of a much older legend.
