Mistake: When Blake refers to the newspaper article, he is holding the paper the wrong way round. He taps the relevant page, but the article is obviously on the page facing the audience. He is actually pointing at the saucy advertisement that was seen to be on the opposing page.
Stan says to mum "make up your mind, do you want a high level grill or low level loo" but if you look in the background she already has a high level grill!!
During the start credits, Anna Karen's name is mispelt as 'Anna Karan'.
