One fine morning, a billionaire was taking a walk with his dog.
Suddenly a man ran out from the bushes in front of him and shot the poor dog three times. The dog died.
The billionaire screamed at the killer, "Why did you do that?".
The killer answered, "Your wife gave me $50,000 and said, "Go, kill that son-of-a-bitch"
The billionaire hugged the killer & with tears in his eyes said...
"I am forever grateful to your English Teacher".
