Buy machine factory
An American manufacturer is showing his machine factory to a potential customer from Albania. At noon, when the lunch whistle blows, two thousand men and women immediately stop work and leave the building.
"Your workers, they're escaping!" cries the visitor. "You've got to stop them."
"Don't worry, they'll be back," says the American. And indeed, at exactly one o'clock the whistle blows again, and all the workers return from their break.
When the tour is over, the manufacturer turns to his guest and says, "Well, now, which of these machines would you like to order?"
"Forget the machines," says the visitor. "How much do you want for that whistle?"
Billing
A doctor and a lawyer were talking at a party.
Their conversation was constantly interrupted by people describing their ailments and asking the doctor for free medical advice.
After an hour of this, the exasperated doctor asked the lawyer, "What do you do to stop people from asking you for legal advice when you're out of the office?"
"I give it to them," replied the lawyer, "and then I send them a bill."
The doctor was shocked, but agreed to give it a try.
The next day, still feeling slightly guilty, the doctor prepared the bills.
When he went to place them in his mailbox, he found a bill from the lawyer.
