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 with her to her boyfriend's apartment to confront him
with her suspicions.

As she arrives, she hears amorous sounds coming from within the apartment.
In a rage she bursts in and finds her boyfriend in an amorous embrace with 
a lovely lady 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 cheating bastard, you're next!"
