StainedA blonde, a brunette and a red head are in the copy room of thier office building when the red head goes over to the corner of the room.
She stands with a puzzled look on her face for a second then says 'This looks like a semen stain'.
The brunette walks over to look as well as touch the stain. She says 'Looks and feels like semen.'
The blonde comes over, looks at, touches, then tastes the stain. She says 'looks like it, feels like it and tastes like it, but it's not from any man in this office.'
