A blonde suspects her boyfriend of cheating on her.  She goes out and buys
a gun.  Sure enough, when she comes home, she opens the door and finds him
in the arms of a redhead.  The blonde is angry--she opens her purse to
take out her gun but as she does so, she is overcome with grief.  She
takes the gun and points it to her head.

The boyfriend yells "No honey, don't do it".  

The blonde replies, "Shut up, you're next".
