A crazed Jeff the Killer fan girl was on out on the town one night and noticed Jeff the Killer...

"Jeffy!!" she screams very cheerfully. 

Jeff gasps and runs out of sight.

This repeats several times until the girl gets all pouty and says, "Jeff, why did you run away from me whenever I called you?"

Jeff replied very irritably, "Goddamn it, girl, I'm trying to take a shit!"
