There was an elderly widow who lived in a large mansion. She was feeling generous when it came to Thanksgiving, so she called up the local military base, and asked to speak with the lieutenant.
"Please send up four nice young men to eat dinner here on Thanksgiving, but please, don't send any Jews. Please, no Jews,"
The lieutenant replied, "No problem ma'am, and I am sure I speak for the army when I say we all appreciate your kindness."
Well, Thanksgiving rolled around, and the widow went to answer the door when it rang. She was surprised to see four black recruits. "But... But... There must be some mistake," she stammered.
One of them replied, "No ma'am, Lieutenant Goldstein doesn't make mistakes."

German scientists dug 50 meters underground and discovered small pieces of copper. After studying these pieces for a long time, Germany announced that the ancient Germans 25,000 years ago had a nation-wide telephone network.
Naturally, the British government was not that easily impressed. They ordered their own scientists to dig even deeper. 100 meters down, they found small pieces of glass, and they soon announced that the ancient Brits 35,000 years ago already had a nation-wide fibre net.
Israeli scientists were outraged. They dug 50, 100 and 200 meters underground, but found absolutely nothing...
They concluded that the ancient Hebrews 55,000 years ago had cellular telephones.
