Guide Dogs

Two men are walking doberman and a chihuahua when they see a restaurant.

They're pretty hungry, so they decide to head in for a bite to eat. Unfortunately, they see a sign out front that says "NO DOGS ALLOWED".

The man with the doberman says "I know what to do, just follow my lead." He throws on a pair of sunglasses and walks in.

The waiter tells him "I'm sorry sir, we don't allow dogs here." The man says "Oh, you don't understand. I'm blind and this is my guide dog."

"A doberman for a guide dog?" The waiter asks, skeptical.

"Yes." The man replies. "Dobermans are very loyal. They're easy to train and protective too. They're born for the job."

The waiter sighs and leads the man to a table.

The second man, excited by this idea, throws on his sunglasses and walks in.

The waiter tells him "I'm sorry sir, we don't allow dogs here." The man says "Oh, you don't understand. I'm blind and this is my guide dog."

"A chihuahua for a guide dog?" The waiter asks.

"A chihuahua?" The man asks. "They gave me a chihuahua?!?"

Transistor

In 1948, the transistor was demonstrated by its inventors, John Bardeen and Walter Brattain, scientists at the Bell Telephone Laboratory in Murray Hill, NJ. It was a simple, tiny device utilizing the electronic semiconducting properties of a germanium wafer. The transistor represented a significant advance in technology. As it was developed over the next few years, it was incorporated into electronic equipment as a functional replacment for the vacuum tube. Such use of transistors provided great savings in space and electrical power consumption. This made possible the small portable, battery-powered transistor radios which were sold to the public by late 1954.*
