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."

A lawyer's dog, running about
A lawyer's dog, running about unleashed, b-lines for the local butcher shop and steals a roast off the counter. The butcher goes to the lawyer's office and asks, ''if a dog, running unleashed, steals a piece of meat from my store, do I have a right to demand payment for the meat from the dog's owner?''

''Absolutely,'' the lawyer responded.

The butcher immediately shot back, ''Good! You owe me $7.99 for the roast your dog stole from me this morning.''

The lawyer, without a word, writes the butcher a check for $7.99. A few days later, the butcher, browsing through his mail, finds an envelope from the lawyer.

The contents read ''Consultation Fee: $25.00.''
