After devouring nearly every scrap of food that she could find at "Billy-Jean's All You Can Eat Buffet", Diane the dog-girl bumps into my Tanya; where almost immediately, the inumimi is mistaken for being preposterously pregnant, rather than just stupendously stuffed.
And as for Billy-Jean, well, since Diane came in and consumed darn-near everything (practically leaving his business penniless), he decided to just quit while he was ahead and go back to law school, much like his mother told him to do to begin with. =p
