Those copyright lawyers are rubbing their hands with glee as today sees what could be the biggest book battle ever.
Lavatory cleaner, Joshua Chimichanga, has filed suit claiming that boy wizard, Harry Potter, is little more than a reworking of his own, as yet unpublished work, Gary Blotter.
He told us:
"When I seen the films I couldn't believe it. It was all my work right down to Gollum and Gandalf!
It's a lift from my series of seven books about boy estate agent, Blotter, who is also a bit magical too"
We suggested that perhaps Joshua is maybe a bit of a crank but he told us:
"Upereemus your arseus - bunch of wankeramus" before running off down the street sitting astride his loo-cleaning mop. Sort of the way kids pretend that they are riding horses if you know what we mean.
Lawyers for J K Rowling have commented:
"Hardly does a week go by when somebody doesn't show up claiming that our client has ripped off their stuff.
JK is chilling listening to mixes of the new album and I don't think that this is going to upset him too much. Not unless Chimichanga scratches the paint-job on his new Roller"
