Businessman is dying
A businessman on his deathbed called his friend and said, "Bill, I want you to promise me that when I die you will have my remains cremated."

"And what," his friend asked, "do you want me to do with your ashes?"

The businessman said, "Just put them in an envelope and mail them to the Internal Revenue Service. Write on the envelope, "Now, you have everything."

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."
