A guy was playing golf one day and got lost. He saw a lady up ahead of him and went to her and said "Can you please help me, I don't know what hole I'm on".

She told him "You are one hole behind me. I'm on 7, you're on 6". He thanked her and continued playing golf. On the back nine he got lost again. He saw the same lady and went to her again kind of embarrassed. "I'm sorry to bother you again but I'm lost again, can you please tell me what hole I'm on".

She told him "You are one hole behind me. I'm on 14. You are on 13". Again, he thanked her and continued playing golf. When he finished he saw her in the clubhouse. He went up to her and asked if he could buy her a drink for helping him out. She accepted. As they were drinking and talking he asked her what she did for a living. "I'm in sales". He replied "no kidding so am I. What do you sell?". 

She: "You'd laugh if I tell". He kept pleading to know what she sold she said she'd tell him if he promised not to laugh. He promised. She said "I sell tampons". He immediately fell to the floor laughing hysterically. She said "You promised you wouldn't laugh". He replied "I'm sorry, but I couldn't help it. I sell toilet paper. I'm still one hole behind you".
