A General questions his GI's
The General went out to find that none of his G.I.s were there. One finally ran up, panting heavily.

"Sorry, sir! I can explain, you see I had a date and it ran a little late. I ran to the bus but missed it, I hailed a cab but it broke down, found a farm, bought a horse but it dropped dead, ran 10 miles, and now I'm here."

The General was very skeptical about this explanation but at least he was here so he let the G.I. go. Moments later, eight more G.I.s came up to the general panting, he asked them why they were late.

"Sorry, sir! I had a date and it ran a little late, I ran to the bus but missed it, I hailed a cab but it broke down, found a farm, bought a horse but it dropped dead, ran 10 miles, and now I'm here."

The General eyed them, feeling very skeptical but since he let the first guy go, he let them go, too. A ninth G.I. jogged up to the General, panting heavily.

"Sorry, sir! I had a date and it ran a little late, I ran to the bus but missed it, I hailed a cab but..."

"Let me guess," the General interrupted, "it broke down."

"No," said the G.I., "there were so many dead horses in the road, it took forever to get around them."

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."
