A linguistics professor was lecturing to his class one day. “In English,” he said, “A double negative forms a positive. It’s a 2-factor case that is not always true however.”
“In some languages, “, he continued,”, 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.’
