Yes, it’s funny that a purple puppet might swear and drink and smoke. And it’s probably amusing that he would hang out with a socially inadequate skinny nerd. But once you get used to those facts, and have nodded in admiration at the production values (the haunted house set works nicely) the new Sammy J and Randy show doesn’t really have a huge amount left to fall back on.

The Inheritance is a rather humdrum affair which kicks off with Randy (as manhandled by Heath McIvor) discovering he is the heir to a vast baronial pile while the pair fill out a census form. But there are inevitable stumbling blocks placed in his path and a twist that you could see coming from a brief skim of the synopsis.

A massive and malevolent gnome is introduced into proceedings which looks as though it’s come straight off the set of Spirited Away while the running catchphrase of ‘it was a different time back then’ becomes fairly tedious on its second airing. Hats off though for the Princess Diana commemorative oven glove and the seemingly ad-libbed shadow puppetry sequence.
