preparation is required. The male must buy a bottle of mustard and hire Ken Griffey Jr. giving him specific directions. Then, while the male is having sex (doggystyle), when he ejaculates in his partner, he gives the signal to Ken Griffey, Jr. who is presumably hidden

the closet spraying mustard in the eye of the male's partner. Having Ken Griffey, Jr. announce himself at the same time is optional.
