Jigsaw puzzle

A group of girls walks into a bar. One of the women tells the bartender to line up a row of drinks for all of them. The gals lift their glasses and toast: "Here's to 51 days!" and they proceed to down their drinks.

Once again, they tell the bartender to "line 'em up" and once again they toast 51 days and down their drinks.

The bartender says: "I don’t get it. Why in the world are you toasting 51 days?"

One of the girl explains: "We just finished a jigsaw puzzle. It had written on the box '2-4 years' but we finished it in only 51 days!"

Alfred Reginald Radcliffe-Brown was an English social anthropologist of the 20th century, whodevelopeda systematic framework of concepts and generalizations relating to the social structures of relatively simple societies. Radcliffe-Brown did much of his early work among traditional people. His first trip to Australia was in 1910; he joined Grant-Watson and D. Bates on an expedition to study Aboriginal tribes. He believed scientific methods should be applied to the study of a society and its common values, this is also known as “collective consciousness.”He also contributed to the study of kinship.
