A new vacuum cleaner salesman knocked on the door on the first house of the street. A tall lady answered the door. Before she could speak, the enthusiastic salesman barged into the living room and opened a big black plastic bag and poured all the cow droppings onto the carpet.

Madam, if I could not clean this up with the use of this new powerful vacuum cleaner, I will EAT all this shit!", exclaimed the eager salesman.

"Do you need chilli sauce or tomato ketchup with that" asked the lady.

"Why, madam?" asked the salesman.

"We just moved in, there's no electricity in the house!"
