If imitation is the sincerest form of flattery, what is parody? We have no idea - except in the case of these 50 Shades Of Grey spoofs, very, very funny indeed.
The book of the moment, which has already sold a million copies and is now being spotted on trains at a rate of ten copies per carriage - has inspired ribbings from all corners of the internet and TV.
Naturally, Twitter has been leading the pack with a series of quite excellent spoof accounts, the details of which are here:
'Inspired' barely covers it - 50 Sheds Of Grey reworks the book's erotic oassages through a DIY prism. Or something.
Former TV football presenter and disgraced sexist Andy Gray gives a blow by blow account of his own sex life which is, unsurprisingly, somewhat more lurid than the book it's parodying.
The book's kinky, long-fingered millionaire has popped up with his own account, and spends more of the time quoting the passages that make hinm look good and replying to adoring females fans who may or may not realise that Christian Grey is a fictional character.
See before. It's sickening, really.
Really, really not for the faint-hearted, 50 Shades of Shit is what EL James would have written if she was a jaded hardcore pornography addict rather than a saucy Mum type.
50 Shades of Mom Porn is a YouTube video making fun of 50 Shades author E. L. James and her readers in a send up of the so-called 'Mommy Porn' phenomenon...
Meanwhile on Late Night with Jimmy Fallon, 50 Shades of Grey Karaoke is exactly what it sounds like, badly-sung songs inspired by quotes from the book...
Another reading finds legendary American voice artist Gilbert Gottfried - you might not recognise the name, but you'll certainly recognise the grating cadence - taking to the mic, with horrific results.
Finally, because someone somewhere had to do an animal parody, check out 50 Shades of Greyhound...
