Bob/Emily/Howard

I got to wondering the other day if there is any 70s Bob Newhart Show slash fiction. A couple naïve Google searches have yielded nothing promising. So, if anybody out there runs across any, I’d be a little bit interested to know about it. And if there isn’t any, why not? Star Trek is an older show, and Kirk/Spock may be the canonical slash. Are we to believe that the idea of Bob/Howard or Bob/Jerry or Bob/Howard/Emily just doesn’t fire anybody’s imagination?
