Here he goes, starting off by bursting into song with a rousing rendition of ‘When the saints go marching in.’

Gail shows her appreciation in the traditional way…

…and Gareth steps in to reduce the problem. Trouble is, covering Fred’s mouth only muffles him, it doesn’t really stop the ‘singing.’

Here’s a better solution – a peppermint. Fred can’t suck and sing at the same time, so he has to hum. Unfortunately, his humming is almost as bad as his singing.

So the next step? Hold his nose. This works a treat – he can’t sing, he can’t hum… unfortunately, he can’t breathe either, but that seems a small price to pay.

Oh, go on then, Fred. You can have your air back. But there you go – how can you stop someone humming? Pinch their nose. Easy.
