In March, 1999 a man living in Kandos (near Mudgee in NSW) received a bill for his as yet unused gas line stating that he owed $0.00. He ignored it and threw it away.

In April he received another bill and threw that one away too. The following month the gas company sent him a very nasty note stating they were going to cancel his gas line if he didn't send them $0.00 by return mail. He called them, talked to them, and they said it was a computer error and they would take care of it.

A grocer put up a sign that read "Eggplants, 25¢ each -- three for a dollar."

All day long, customers came in exclaiming:
"Don't be ridiculous! I should get four for a dollar!"

Meekly the grocer capitulated and packaged four eggplants. The tailor next door had been watching these antics and finally asked the grocer, "Aren't you going to fix the mistake on your sign?"

"What mistake?" the grocer asked. "Before I put up that sign no one ever bought more than one eggplant."
