Vacuum cleaner
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 s...! " exclaimed the eager salesman.
Do you need chilli sauce or ketchup with that" asked the lady.
The bewildered salesman asked, " Why, Madam? "
"We just moved in, & there's no electricity in the house!"
