A butcher saw a Lawyer passing by his shop one day, and asked him:
Bill. What would you do if a dog came in and stole your meat?
Lawyer replied: why? Of course, I’ll make the owner pay for it!
The butcher said: If that is so, now you owe me $15 because it is your dog.
The Lawyer replied: very well, just deduct the $15 from the $25 you owe me for the advice, I’ll collect the remaining $10 the next time I pass by here.
