On April 18, 1926, Sinclair Lewis mounted the pulpit of a Kansas City church, took out his watch, and defied God to prove his existence within 10 minutes by striking him dead.

God spared him.

George Bernard Shaw had once made the same challenge but gave God only three minutes. “I am a very busy man,” he said.
