So the sergeant major was out running some PT with his 10 year old boy. The boy says "Hey, Sergeant major! I'll betcha $50 when we get around this hill, there's a bull screwing a heifer right here in town!" The old man says "You're on!" but when they rounded the hill, it was exactly as described. Next morning, the sergeant major calls the kids teacher. "Excuse me, ma'am, but it seems my son has developed quite a gambling habit. But I can't get him to stop because he always wins! Do you have any ideas?" She replies "Not right off the top of my head, but I'll think about it a few days. Maybe I can help. Later, as the class arrives, the kid approaches the woman "Teacher, teacher! I'll bet you $50 you're wearing pink panties right now!" The woman, startled, answers "No way! Not today!" The next day, she decides to wear red panties, and the kid bets she has red panties on, and she again declines. Same for the day after that, with white panties. But that night, she has a brainstorm! Next day, the kid comes up "Teacher, teacher! I'll bet you $50 you're wearing black panties right now!" She says "You're on, kid!" triumphantly raising her dress to reveal she's not wearing any panties at all. The kid was rather upset, kicking desks and throwing chalk, but he eventually paid up. The teacher calls the sergeant major excitedly, saying "Guess what! I got him to lose a bet!" The sergeant major, astonished, asks "Oh, yeah? How'd you manage that?" She explains that the kid bet $50 she was wearing black panties, but she showed him that she wasn't wearing any panties at all. Now it's the sergeant major's turn to be upset, cussing like a sailor. The teacher, perplexed, asks "What's the matter?" The sergeant major replies with disgust "He bet me $500 this morning that he'd see your pussy before the day was out!"
