A old lady hears a knock at the door and opens it.
"Good Morning!" a salesman says.
"If I could take a couple of minutes of your time, I would like to demonstrate the latest high powered vacuum cleaner."
"Go away! I haven't got any money!"
The woman tries to close the door but the eager salesman quickly wedges his foot in the door and forces his way inside.
"Don't be so hasty!" the salesman says. At least let me show you my demonstration!"
The salesman grabs a bucket of manure & dumps it all in a pile on the woman's carpet.
"Now if this vacuum doesn't pick up this entire pile without a trace, I will personally eat the remainder of whatevers left." says the man
"Well, I hope you got a big appetite," Saya the old lady. "Because they turned off my power this morning!"
