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."

Air Heads
Poor Jim is killed in a Boston automobile accident, but happily he goes to heaven where he gets to meet God and asks God if he can ask him a few questions.

"Sure. Go right ahead," says the Almighty.

"OK," Jim says, "Why did you make women so pretty?"

"So you would like them," God replies.

"All right then," Jim nods, "but come you made them so nice and soft and curvey?"

"So you would LOVE them," God replies.

Jim ponders a moment and then asks, "But why did you make them such air heads?"

God replies, "So THEY would love YOU!"
