Plumber's Don't Wear Ties - It's essentially a slideshow with bunch of pictures edited using MS Paint masquerading as a visual novel made for a failed console 3DO, coupled with terrible voice acting and one train wreck of a plot. It's actually worth checking out just to see how laughably atrocious it is.
JESUS GOD. I still wonder if that was made seriously or as a joke. Like there's no way a coherent human being could look at that and feel totally satisfied with it unless it was made to be bad on purpose.
