Funniest Christmas novelty song?

Britain is plagued by Christmas Song anthologies that get replayed every year in places like supermarkets - most come from pop novelty records of the 1970s or 80s. 

None of the playlist novelty songs are much good - although I have a soft spot for Boney M "Mary's Boy Child" - but the one really enjoyable example of this kind of seasonal offering from the 70s/80s is never played in public nowadays, and seems to have been officially "forgotten"... 

For reasons that will become pretty obvious when you listen. 

I mean, of course, that comic masterpiece of smut and innuendo from 1974 by then UK's favourite family-friendly humourists, The Goodies: "Father Christmas Do Not Touch Me"; initially just the B-side of a forgettable single that reached #13 in the charts, then flipped into a Double-A side...  

Not even its most fervent advocates could say that FCDNTM captures the true Christmas Spirit, nor even that it instils good values or admirable ideals. 

But I just listened to it again; and again found myself almost crying with laughter - as much at the just-right background accompaniment, in the gaps between the "singing", as the actual song. 

Merry Christmas to one and all!
