A guy walks up to the airline ticket counter and says, "I'd like to buy a ticket to Philedalphia and I have 3 bags to check. However, I want one bag to go to New York, one to Los Angeles, and one to Miami." The ticket person says. "I'm sorry Sir, we can't send your bags to 3 different places, especially since none of the places are where you are flying to." So, the guy says, "Well, you did it the last time I flew, and I didn't even have to ask!"
