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."

"Well," Bubba began, "We wuz havin' a good time drinking, when my cousin Ray picked up his shotgun and said, 'Hey, der ya fellows wanna go hunting?'"

"And then what happened?" the officer interrupted.

"From what I remember," Bubba said, "I stood up and said, 'Sure, I'm game.'"
