Editor's note:Do you need something to smile about? Every day, WND selects the best joke offered up by readers and contributors to its Laughlines forum and brings it to you as the WND Joke of the Day. Here is today's offering:
A linguistics professor was lecturing his class.
"In English," he explained, "a double negative forms a positive. In some languages, such as Russian, a double negative is still a negative."
"However," the professor continued, "there is no language wherein a double positive can form a negative."
A voice from the back of the room piped up. "Yeah, right."
