2012 – Danny Baker’s Doorbells Part 1. These had me in tucks, it starts half way through with Carol’s very funny doorbell whose batteries were running out… and then Danny finds Carol’s doorbell was playing in so many songs ;-).
2009 – Catherine Tate: The Offensive Translator. Oh terribly politically incorrect, but sorry, this had me in stitches.
2008 – The Inbetweeners – “Thanks, Phil” – so the character Will gets over-confident and calls the teacher Mr Gilbert by his first name Phil. The rest is a comedy classic.
