A man walks into a restaurant and notices a large sign on the wall: "$500 IF WE FAIL TO FILL YOUR ORDER!"
When his waitress arrives, he orders elephant tail on rye.
She calmly writes down his order and walks into the kitchen where, a few seconds later, all hell breaks loose!
The restaurant owner comes storming out of the kitchen. He runs up to the man's table, slaps five $100 bills down and says, "You got me that time buddy, but I want you to know that's the first time in ten years we've been out of rye bread!"
