Justin Lee Collins, Freema Agyeman, Ozzy Osbourne. - S12.E9

There was a time when Ozzy liked nothing more than to tuck in to a bat's head for a snack, these days he's far happier with a delicious butter substitute. We all mellow with age. I'm worried that Justin Lee Collins will end up as the latest canine member of Ozzy's family due to his cartoon dog-like appearance. I'm sure he wouldn't get away with using the floor as a toilet as easily as Ozzy's real dogs seem to.
