Grandma's Boyfriend

A 5-year old boy went to visit his grandmother one day. While playing with his toys in her bedroom while grandma was dusting furniture, he looked up and said, "Grandma, how come you don't have a boyfriend?" Grandma replied, "Honey, my TV is my boyfriend. I can set in my bedroom and watch it all day long. The TV evangelists keep me company and make me feel so good.
The comedies make me laugh. I'm so happy with my TV as my boyfriend." Grandma turned on the TV and the picture was horrible. She started adjusting the knobs trying to get the picture in focus. Frustrated, she started hitting on the backside of the TV hoping to fix the problem. The little boy heard the doorbell ring so he hurried to open the door.
When he opened the door, there stood Grandma's minister. The minister said, "Hello son is your grandma home?"
The little boy replied, "Yeah, she's in the bedroom bangin' her boyfriend."

Dry-cell patent

In 1887, German scientist, Dr. Carl Gassner, was issued a U.S. patent (No. 373,064), the first in the U.S. for a “dry” cell. Gassner had already patented his invention in Germany (No. 37,758) on 8 Apr 1886, and also in Austria, Belgium, England, France and Hungary in the same year. The sealed zinc shell which contained all the chemicals was also the negative electrode. Later, he improved the shelf life of the battery by adding zinc chloride to the electrolyte to reduce corrosion of the zinc shell. Gassner's battery was much like the carbon-zinc, general-purpose batteries sold today. By 1896, the National Carbide Company (later Union Carbide and Eveready) produced the first consumer dry cell battery. Two years later, the company made the first D cell.«[Image: The six-inch, 1.5 volt Columbia Dry Cell marketed by NCC in 1896.]
