A man walked into a restaurant...
A man walked into a restaurant and saw a sign that read, "We'll give you $300 if we're unable to serve you any entree you order."
He sat down and told the waitress he wanted elephant liver on rye.
The waitress took the order and left.
All of a sudden, the man heard terrible noises coming from the kitchen - the sound of feet stamping, screaming and the banging of pots and pans.
It went on and on.
The noise finally stopped, and the cook appeared from the kitchen.
He slapped down $300 in front of the customer and said, "I can't believe it. We're out of rye."

ENIAC first operatedIn 1946, the world's first electronic digital computer, ENIAC (the Electronic Numerical Integrator and Calculator) was first demonstrated at the Moore School of Electrical Engineering at the University of Pennsylvania, by the late John W. Mauchly and J. Presper Eckert. The ENIAC machine occupied a room 30 by 50 feet. Its birth lay in WW II as a classified military project known only as Project PX. The ENIAC is historic because it laid the foundations for the modern electronic computing industry. The ENIAC demonstrated that high-speed digital computing was possible using the vacuum tube technology then available. Built out of some 17,468 electronic vacuum tubes, ENIAC was in its time the largest single electronic apparatus in the world. |
