Tommy, a lawyer had a dog and it was running round loose and it made a bee-line for a butchers shop and steals a joint of beef.

The butcher goes to Tommy's office and asks, "if a dog running loose steals a joint of beef from my shop, do I have a right to demand payment for the meat from the dog's owner?" Tommy answers, "Absolutely."

"Then you owe me £10.50. Your dog was loose and stole a joint from me today."

Tommy, without a word, writes the butcher a cheque for £10.50.

Three days later the butcher opens the mail and finds a bill from Tommy  "£100 for legal consultation"
