£50 prize to the best letter. One of Brooker's one-shot cartoons caused the magazine to be pulled from the shelves of many British newsagents. The cartoon was titled "Helmut Werstler's Cruelty Zoo" and professed to be an advert for a theme park created by a Teutonic psychologist for children to take out their violent impulses on animals rather than humans. It was accompanied by photoshopped pictures of children smashing the skulls of monkeys with hammers, jumping on a badger with a pitchfork, and chainsawing an orang-utan, among other things. The original joke was supposed to be at the expense of the Tomb Raider games, known at the time for the number of animals killed, but the original title, "Lara Croft's Cruelty Zoo", was changed for legal reasons.

The Guardian withdrew the article from its website and published and endorsed an apology by Brooker. He has since commented about the remark in the column stating: Brooker left the "Screen Burn" column in 2010. In the final column, he noted how increasingly difficult he found it to reconcile his role in mainstream media and TV production with his writing as a scabrous critic or to objectively criticise those he increasingly worked and
