Sam's earliest days as a 10-cent-store owner, he would never sell a Hula-Hoop because a Hula-Hoop was branded and came from Wham-O, and you'd have to pay Wham-O something for having developed the product. Sam looked at it and said, "It's a round piece of circular plastic. Get somebody to make us a round piece of circular plastic, and we'll call it something else and we'll sell it for half the price!" Huey : There are so many exact opposites, and there are so many parallels. Sam had multiple myeloma. And he, like Steve, sought out all kinds of exotic cures. Brought people in from Germany. Isaacson : Both of them did not believe that the normal rules applied. Huey : To anything. Isaacson : To anything. For Steve and I think for Mr. Walton, it probably worked 90% of the time. Huey : My two favorite Sam Walton breaking-the-rules stories: One time we're flying, and the air traffic controller comes on the radio and says, "You're in unauthorized air space." Got the tail number and all. And Sam just turns off the radio. We keep flying, he's got his spreadsheets taped to his leg, and we're looking for a store -- he's looking for the worst-performing store because that's where we're going to land. And we're flying, and the radar's there, and it's green and it's yellow and it's red, and I'm like, "Sam, why are we flying to the red?" and he said, "Because that's the quickest way."
