A linguistics professor was lecturing to his class one day. "In English" he said, "a double negative forms a positive. In some languages, 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."
[Inkspot] If I can divert the subject from bad jokes for a minute, what makes a series of Big Brother good or bad? What is a "good" contestant (from the point of view of the people who watch it, rather than the producers)? On what grounds do people vote for someone to be evicted? In other words, how does the whole thing work?
