A pious man who had reached the age of 105 suddenly stopped going to synagogue. Alarmed by the old fellow's absence after so many years of faithful attendance the Rabbi went to see him. He found him in excellent health, so the Rabbi asked, "How come after all these years we don't see you at services anymore?"The old man looked around and lowered his voice. "I'll tell you, Rabbi," he whispered. "When I got to be 90, I expected God to take me any day. But then I got to be 95, then 100, then 105. So I figured that God is very busy and must've forgotten about me, and I don't want to remind Him!"

A lecture about English
A linguistics professor was lecturing to his English class one day. "In English," he said, "A double negative forms a positive. In some languages, though, such as Russian, a double negative is still a negative. However, there is no language wherein a double positive can form a negative."

A voice from the back of the room piped up, "Yeah, right."
