When the insurance price comparison site comparethemarket.com started advertising using fake meerkats bemoaning that people were confusing it with their comparethemeerkat.com site, little did they know how well it would catch on. Especially the creature popping up at the end and saying "Simples". It has bugged me on zoo visits, where kids always pop up and utter the line.
I don't know if it has helped the actual company, but apparently there has been a big increase in the number of people adopting meerkats in zoos and animal parks.
And, of course, the company just
had to set up an actual comparethemeerkat.com website.
They try to deflect you back to the insurance site, but you can still compare meerkats if you persist! Try it here:
