Stiff Neck

A five year old boy comes to visit his grandparents and notices his grandfather sitting on the porch, in the rocker, wearing only a shirt, naked from the waist down. "Grandpa, whatcha' doing? You're weenie's out and everybody can see!" he exclaimed.
Grandpa looked off in the distance, not answering.
"Grandpa, whatcha' doin' sitting out here with no pants on?" he asked again.
Grandpa looked at him and said, "Son, last week I sat here with no shirt on, Just watching the cars go by.... and I got a stiff neck. This is your Grandma's idea."

First pure software patent

In 1981, Satya Pal Asija was the first in the U.S. to receive a patent for computer software for his computer program Swift-Answer (an acronym for "Special Word Indexed Full Text Alpha Numeric Storage With Easy Retrieval") that allows users to retrieve narrative information from computers in a human-like manner. The program responds to a user's questions with the most likely answer - despite the user's errors in syntax, punctuation, spelling, and grammar. The user needs no computer programing skills. His application for the patent took seven years to issue. (U.S. No. 4,270,182). He published a book on his experience, How to Protect Computer Programs - a Case History Of The First Pure Software Patent, in 1986.
