It has been suggestes that there are similarities between Slurls and Googlewhacks.
OK, let's see what they have in common. Both are on the web, about language, unintentional, and difficult to find.
But they part company when it comes to sense of humour. Whereas your average Googlewhacker hangs out in libraries guffawing at "indiana paroxetines" and "insudate electrons", the Slurler will be seen at the local mall asking shoppers if they've been to Pen Island yet. That's what Slurling is all about, if it ain't distasteful it's hardly a proper Slurl.
* Don't know what a Googlewhack is? It's a two word search that when typed into Google produces one, and only one, result. Google has several billion web pages in its index, so they are pretty rare. See www.googlewhack.com for examples like "episcopal brachiosaur" and "primp schadenfreude". And if you haven't read/seen Dave Gorman's Googlewhack Adventure, you are missing out. The man is a genius. Here is his stuff on Amazon.com and on Amazon.co.uk.
