New Gorilla in Bar

A black man enters a bar with his gorilla. He says to the bartender, "I would like a beer, and a gin and tonic for my girlfriend here."

The bartender looks at him like he's nuts and says, " I sorry but I don't serve Gorillas in this bar."

The man has an idea. He takes his girlfriend home and shaves her head, gives her a wig, dress, and makeup. Then he returns to the same bar. He places the same order and this time the bar tender gives it to them.

They go and sit in a corner while the bartender turns to his friend and says, "Damn! Did you ever notice how all the good looking Iraqi ladies that come in here, always seem to be with black men.

Telescope lens

In 1947, after 11 years of grinding and polishing a 200-inch diameter telescope lens for the Mount Palomar Observatory was completed at the California Institute of Technology. This lens, the first of its size made in the U.S., began when 20 tons of molten glass at 2,700 deg. Fahrenheit were poured into a ceramic mold at Corning Glass Works, N.Y. on 2 Dec 1934. The glass lens was allowed to cool only one or two degrees per day over the next eleven months, and then brought to room temperature. The telescope in which the lens was mounted was named the Hale Telescope in recognition of the late Dr. George E. Hale who had initiated the project. The completed telescope was first used on 1 Feb 1949 by taking pictures of a Milky Way constellation.
