Cheerleaders Vs. St. Peter

A high school cheerleading squad were in a bus that shot off a cliff killing all onboard... Don't laugh yet! 
When they got to heaven they were met by St. Peter at the gate.
He asked the first girl if she had done anything with any boys, and she said to St. Peter that she had held a boys hand, so St. Peter told her to wash her hands in the holy water before entering heaven. 
St. Peter then asked the second girl the same question, and she said she had kissed a boy, so Peter told her to wash her lips in holy water before entering heaven. 
Then Peter noticed two farther back in line girls arguing over their position in line. 
Peter asked the girls what was going on, and the one girl said to him, "I'm not gargling that after she sits in it."

Ethernet

In 1973, Robert Metcalfe wrote a memo describing a way to transmit data from the early generation of personal computers to a new device, the laser printer. He called his multipoint data communications system Ethernet, and today it continues to dominate as the standard computer network. A U.S. patent for "a Multipoint data communication system with collision detection" was issued 13 Dec 1977 ( 4,063,220) to Metcalfe, and others who developed the Ethernet. The patent was assigned to the Xerox Corporation.
