three women are walking near the tennis courts of a private club. There is a signboard where some man is changing clothes, but he can only be seen from the waist down.

1st woman: "he shouldn't be changing there! At least it isn't MY husband!"
2nd woman: "..well, it sure isn't MY husband either!"
3rd woman: "You know, I think we should call security...he isn't even a member of the club!"
