Raging Blonde

A blonde suspects that her boyfriend has been cheating on her for some time. In a fit of rage she visits a local gun shop and buys a pistol. She then takes the gun to her boyfriend's apartment to confront him with her suspicions.
As she arrives, she hears amorous moans coming from within the apartment. In a rage she bursts in and finds her boyfriend making love to a woman on the floor in front of her.

She reaches into her purse to retrieve the weapon and as she does so, she is overcome with grief. In her grief she raises the gun to her own head. The boyfriend jumps up and begins to plead with her not to end it all. She cocks the gun, looks him angrily in the eye and says, "Sit down and shut up, you're next!"
