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."

Ball Rolling
Three men were waiting at Heaven's gates. Peter says, "OK, guys, pretty much anything goes up here, but whatever you do, never lie, or you will spend the rest of eternity with the ugliest women in the universe."

So they all agree and are admitted in. The first guy makes it a week before he lies about how rich he was on Earth. Bam! Right at his side appears the ugliest woman he had ever seen.

The second guy makes it another couple weeks before he lies about how smart he is. Bam! At his side appears the second ugliest woman in the universe.

So the first two guys are walking around with their monsters of women when they see their third friend walking with the hottest woman ever conceived by man. The first two guys say in unison, "How did you land with that babe when we get stuck with these nasty women?"

He nudges the babe and says, "Tell them."
She says to the first two guys, "I lied."
