Two brothers, aged 9 and 5, try to buy tampons at a pharmacy. They take them to the counter and the pharmacist says, “Are these for you?” The older brother says, “They aren't for me, they’re for my brother.” Very confused the pharmacist asks, “But, why does your brother need them?”, and the older brother says, “Well, the lady on the TV said if you use these you can swim and ride a bicycle and he can’t do either of those things.”
