You will find me with four legs, but no hair. People ride me for hours, but I don't go anywhere. Without needing to be tugged, jerked or turned on, I always manage to be ready for work. What am I?

Vacuum tube

In 1906, Dr. Lee DeForest (26 Aug 1873 - 30 Jun 1961), one of the “fathers of radio,'' announced his three-element electrical vacuum tube (now known as a triode) to a meeting of the American Institute of Electrical Engineers He had discovered that when a mesh, or grid, of wire was placed between the filament and collector “plate” in a diode tube (first made by J. Ambrose Fleming, 1904), a large voltage-amplifying effect could be produced. DeForest patented this vacuum tube on 15 Jan 1907. The ability of this tube to amplifiy weak signals was an invention as great as radio itself, because it made long-distance communication possible.[Image: early DeForest Audion]

A pastor's wife was expecting...

A pastor's wife was expecting a baby, so he stood before the congregationand asked for a raise.
After much discussion, they passed a rule that whenever the preacher'sfamily expanded, so would his paycheck.
After 6 children, this started to get expensive and the congregation decidedto hold another meeting to discuss the preacher's expanding salary.
A great deal of yelling and inner bickering ensued, as to how much theclergyman's additional children were costing the church, and how much moreit could potentially cost.
After listening to them for about an hour, the pastor rose from his chairand spoke, 'Children are a gift from God, and we will take as many gifts asHe gives us.
Silence fell on the congregation.
In the back pew, a little old lady struggled to stand, and finally said inher frail voice, 'Rain is also a gift from God, but when we get too much ofit, we wear rubbers.'
The entire congregation said, 'Amen.'
