I have shirt with a stain that looks like the virgin Mary.  I'm afraid to fall asleep it now.  I might wake up with candles on my chest.
I wonder if these people are connisoures of fine stains?  I wonder if they collect them or something?  Maybe they have skid marked underwear hanging on their walls.  What if they found a pile of dog poo that looked like the virgin Mary?  
I've been looking in the DSMIII, but I still can't figure out what mental illness this falls under. I'm stumped!
