Life imitates Python

Back in 1974 these people won the Most Awful Family in Britain competition.  Their domestic behavior, as documented by Monty Python's Flying Circus, was mild compared to the unnamed "family" of twelve to fifteen people (no one is sure) who spent their holidays in New Zealand, where they shoplifted, ran out on restaurant bills, trashed a hotel room and eventually got deported.
