Bob...gay?

Maybe it's just because the actor who played him (Daniel Greene I think is the name) did an absolutely horrible, horrible job, but I kind of got the vibe that he was gay.

He is ignoring Patty, who seems to be really the only woman in town. And Elvira gives him plenty of opportunities to be with her, and she basically has to force him to do anything with her.

It would actually work for the film because it could be said that Elvira is so charming that she could even turn a gay man straight (even just for a little while).
