Anyone into golf?

A man is out on the course, and suddenly forgets what hole he is playing. Walks to the next tee and asks a member of the female foursome 'Would you mind telling me what hole I'm on? I'm right in back of you.' The woman answers, 'We are on five, so you must be on four.' The man continues play and when he gets on the back nine, he again forgets where he is. Again asks the ladies up ahead the same question. They again tell him what hole he is on. The round ends, and they are all enjoying drinks in the clubhouse. The gentleman apologizes for his lapses of memory, and strikes up a conversation with one of the women. The talk gets around to what they do for a living, and they are both sales reps. The woman is embarrassed to tell the man who she works for, but finally confesses to being a sales rep for Tampax. The man laughs out loud, and says 'I'm still a hole behind you. I'm a rep for Preparation H'.
