A man was walking along a Cali...

A man was walking along a California beach and stumbled across an old lamp.

He picked it up and rubbed it and out popped a genie. The genie said "OK, OK. You released me from the lamp, blah blah blah. This is the fourth time this month and I'm getting a little sick of these wishes so you can forget about three. You only get one wish!"

The man sat and thought about it for a while and said, "I've always wanted to go to Hawaii but I'm scared to fly and I get very seasick. Could you build me a bridge to Hawaii so I can drive my car there?"

The genie laughed , "That's impossible. Think of the logistics of that! How would the supports ever reach the bottom of the Pacific? Think of how much concrete-how much steel! And the maintenance of that bridge! No - think of another wish."

The man said OK and tried to think of a really good wish.

Finally, he said, "I'm married to a redhead. So, I wish that I could understand her... know how she feels inside and what she's thinking when she gives me the silent treatment...... know what she really wants when she says 'nothing'... know how to make her truly happy......I want to know how she can be so damn sexy one second and be the devils daughter, the next. I really want to understand her and how she thinks!"

The genie said, "You want that bridge with two lanes or four?"

Alfred Binet

Died 18 Oct 1911 at age 54 (born 8 Jul 1857). French psychologist who was a pioneer in the field of intelligence testing of the normal mind. He took a different approach than most psychologists of his day: he was interested in the workings of the normal mind rather than the pathology of mental illness. He wanted to find a way to measure the ability to think and reason, apart from education in any particular field. In 1905 he developed a test in which he had children do tasks such as follow commands, copy patterns, name objects, and put things in order or arrange them properly. He gave the test to Paris schoolchildren and created a standard based on his data. From Binet's work, "IQ" (intelligence quotient), entered the vocabulary. The IQ is the ratio of "mental age" to chronological age, with 100 being average.[Although some sources give birthday as 11 Jul, both Enc. Brit. and Dict. of Sci. Biog. give born 8 Jul 1857.]
