In the last volume Harry awakens and discovers that he's been dreaming and that he's really an extremely bored accountant in a mid-sized firm dealing in plumbing fixtures. Hermione is his ex-wife and this weekend is his turn to take care of the four kids, Ron Weasley is his duck hunting/beer drinking buddy who works for the city driving a garbage truck, and Cho Chang is a waitress at their favorite watering hole. Malfoy is the owner of the firm Potter works for, Crabbe and Goyle are two extremely incompetent co-workers.

The half-blood prince, of course, is Potter's half-Airedale, half-dachshund dog, whose full name is Prince Of Piddles.
