A Real Watch Dog
A blind man walked into a bank with his seeing-eye dog that guided him everywhere. He walked into the center of the bank floor, took the dog by the chain, and started swinging him around his head.

Everyone stopped what they were doing and looked. The other customers were very confused and some very upset at the way the animal was being treated. One of the tellers ran up to the blind man and asked, ''Sir, what are you doing!?!''

The man turned toward the teller and simply said ''Looking around.''

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."
