Wot you \'arrin\' at, luv?

Because nightmare fuel is the only energy source whose cost is not on the rise, a couple of Brits wore faceless masks to Wimbledon to scare everyone out of their skivvies.

With the blankest of blank expressions on their faces, these mysterious figures have been popping up in the most unlikely of places.

The faceless mutants have a penchant for A-list celebrity bashes and have been spotted at Elton John's White tie ball and Harrods summer sale, opened by Sex and the City star Kim Cattrall.

With a membrane of skin stretched tightly over their eyes, noses and mouths, the alien-like figures were most recently snapped 'watching' a match perched on Murray Mount at Wimbledon.

The masks have tiny perforations that allow the wearer to see and breathe and all that essential stuff. Hopefully they're somewhat resistant to fire, because if I spot any of these things, my trusty blowtorch will not be stayed. But then I usually aim at the genitals first anyway.
