Three women are in a gym locker room dressing up to play tennis when suddenly a guy runs through the room wearing nothing but a bag over his head.
He passes the first woman, who looks down at his penis. "He's not my husband," she says.
He passes by the second woman, who also looks down at his penis. "He's not my husband either."
He passes by the third woman, who also looks down as he runs by her.
"Wait a minute," she says. "He's not even a member of this club."
