Where can I find jokes?

One day, an American, a Japanese and an aborigine were walking on the road. Suddenly, the American arm rang. He pressed his arm and said, this is our American high technology. You can answer the phone by implanting a chip in your hand. After walking for a while, the Japanese palm rang. He said: This is the latest high technology in Japan. If you implant a chip in your palm, you can answer the phone and listen to the radio. The aborigines walked into the toilet in frustration and came out with a piece of toilet paper in their ass. They don't understand, said the native, a fax has just arrived!
