Does this happen outside of Belgium?
My wife, Lieve, is a big fan of British detectives. Nothing like a good Morse episode on a Saturday night. Unfortunately, that one particular series has ended now. Midsomer Murders is trying hard to follow into Morse's footsteps and the series does do a good job. So... tonight, Lieve is enjoying another new episode of the series. And all of a sudden, I hear Christmas music. Sometimes I think it is a specialty of our Belgian programmers to schedule Christmas episodes of a series in periods other than Christmas... A Christmas special of The Simpsons in the middle of summer? No problem! It gets funnier... The online tv guide for Canvas even introduces the episode: "With Christmas approaching..." I wonder... is this a Belgian thing?
