One fine day, a billionaire was walking his dog.
Suddenly a man ran out from the bushes in front of him and shot the poor dog three times.
The billionaire screamed at the killer, "Why did you do that?".
The killer answered, "Your wife gave me $50,000 and said to "Go kill that son-of-a-bitch"".

The billionaire hugged the killer & said .................. !!

"I don't know who your English teacher was, but I am forever grateful to her".
