### Devil at the congregation

One bright, beautiful Sunday morning, everyone in the tiny town of Johnstown got up early and went to the local church. Before the services started, the townspeople were sitting in their pews and talking about their lives and their families.

Suddenly, the Devil himself appeared at the front of the congregation. Everyone started screaming and running for the front entrance, trampling each other in a frantic effort to get away from evil incarnate.

Soon everyone was evacuated from the Church, except for one elderly gentleman who sat calmly in his pew, not moving, seemingly oblivious to the fact that God's ultimate enemy was in his presence. Now this confused Satan a bit, so he walked up to the man and said, "Don't you know who I am?"

The man replied "Yep, sure do."

Satan asked "Aren't you afraid of me?"

"Nope, sure ain't," said the man.

Satan was a little perturbed at this and queried "Why aren't you afraid of me?"

The man calmly replied "Been married to your sister for over 48 years."

### Roger Revelle

Died 15 Jul 1991 at age 82 (born 7 Mar 1909). Roger Randall Dougan Revelle was an American oceanographer whose research interests integrated study of the sea with geography, geology, geophysics, and meteorology. After WW II, as a commander in the Naval Reserve, he supervised oceanographic measurements during the Operation Crossroads (1946) atom bomb tests off Bikini. He did pioneering work in deep-sea drilling and measuring of the upward flow of heat through ocean floors. His tectonic studies in the Pacific Ocean helped to advance the theory of ocean floor spreading. Although in 1955, he was not alarmed about using the oceans as a depository for radiactive wastes, Revelle expressed an early concern about global warming (1957) due to increasing carbon dioxide to the atmosphere.«
