A woman is visiting a boxing gym

 

 She’s there for an exhibition match and sees a large muscular man in one corner of the ring. Who is that? She asks. The trainer steps over and says why that’s one punch Willie he’s our star. He knocks out every opponent with his first punch. Wow! she exclaims. He’s amazing. She looks across the ring and sees man after man lined up to fight Willie. Sure enough, as each man enters the ring. Bam. One hit and they’re out. She asks the trainer why they are all lined up just to get knocked out. He says Ma’m Why that’s just the punch line.
