So I go out there, win my match, win my contract on Raw back, and I figure I’m going to go back to my shorts the next week. But walking back from the ring, Vince McMahon stops me and says, ‘You look great in trunks, kid. You’ve got great legs. You should be wearing trunks.’ I’m like, but I don’t like the trunks. I want to look different. I want to stand out. And he said to me, ‘You already stand out enough. Now we’re going to make you serious.’ I really didn’t want to do it, but when Vince McMahon comes up to you and tells you that you have great legs and that you need to be wearing trunks, well, you’re wearing trunks
