This competition can throw up some pretty strange performances. And then there's the complete freakazoid wild cards that make you wonder just how they got this far through the process.
Take Mezzo Tronic. You can tell, just like their song title, that they really mean it. But quite what it is that they mean is not entirely clear. Oh, and keep a look out for the haunted look on the old lady's face a few seconds after they finish their performance. She looks right into your soul, man. A priceless three minutes of Eurovision history.
