Dilbert: When do you expect to come out with a new model?
Vendor: In about two months.
Dilbert: I'll wait and buy the new model.
Vendor: Did I say two months? I meant never.
Dilbert: Never? That must mean your company is going out of business and won't support this product.
Vendor: What's a length of time between two months and never that would cause you to buy now?"
Dilbert: One year.
Vendor: Our new model comes out in a year.
Dilbert: I'll wait until then.
Vendor: You're the worst customer ever."
