The preamble to this is that I'm making a big quiz for work, and wanted a sound round. To that end I've just found a "Kazoo Christmas" album on Spotify. Hit play, and almost immediately had to push my face into my scarf and try to laugh quietly. I've spent a good few minutes almost crying with laughter at a kazoo tooting out Deck The Halls. I had no idea my sense of humour was so poor!! Mumsnetters, what is your "utterly stupid but deeply hilarious" Thing?
