The Gang Goes to a Fun House For Halloween

[britinmanor]

I have been searching for this story, and pulling out all the bizarre writers I can think of, to no avail. It's Halloween and Justin suggests going to this funhouse for Halloween. The group parts during a tour in a tunnel. Someone is actually there to terrorize Brian and Justin, and Brian just about goes crazy thinking somene is torturing and killing Justin. Mel witnesses Brian's reaction, and Craig is actually locked in a room and forced to watch all this. It's actually one of Craig's employees who's dressed as a clown and is doing this because Justin and Brian are gay.

Thanks for your help.
