Talking about a thermus.

[flying dog]

The three world's geatest engineers were assembled to nominate THE best invention.

 

The American said the car. "Without the car or vehicle, we wouldn't have the ability to move things and society as we know it wouldn't exist."

 

The English said electicity. "As much as you are correct, electricity gives us light, warmth, the ability to communicate. It is truely fantastic."

 

The Irish said the thermus.

 

The other two look at him perplexed. "WHY?"

 

He looks at them. "Well, one day I go to work and it is going to be cold. I put in hot coffee and when it is lunch time, I pour the coffee and it is still hot."

 

The other two look at him.... "And.....?"

 

The Irish engineer continues. "Well, on another day, it is going to be hot. So I put cold water in and take it with me. When I am thursty, I pour the water and it is still cold. How does the thermus know what to do?"
