An electric shock!
A vacuum cleaner salesman knocked on Sally's door.
"Let me demonstrate this vacuum cleaner on your floor."
"My present vacuum cleaner removes every bit from my carpet pile."
"Madam I promise you ,it will only take a while."
"Oh very well ,"she said and she let him in.
He immediately emptied a load of horse manure from his bin.
"If my vacuum cleaner does not remove all of it,
I personally will eat every left behind bit."
"Well I hope you have got a great appetite,
Because they cut off my electricity last night!"
