I have a puking JOL with something gross coming out of the mouth. Sometimes I use gucomole dip, spinach dip, hominy salad, etc.
I also use a small skeleton and lay out cold cuts inside it.
Brain mold with yucky looking stuff, etc.
We have served freshly flayed flesh before which is a big brisket that is smoked on the grill and comes out looking black or charred like a burned corpse. It is really cool looking on a table with a skeleton skull a the top of it.
Those are awesome! I especially liked your Halloween Ribs. We didn't go all out like that (it doesn't take much to gross out a couple 7-year olds). But If I ever do this when I have kids, it's gonna be like this.
