When I first got the internet at home (on a 56k modem, attached via a serial port to my AMD486,) I came across a forum who had been terrorised by The Eyebrow Thief.
Each member of the forum had a photo of themselves as their avatar, and The Eyebrow Thief would just reply to peoples questions with an edited photo of the asker – edited so that the askers eyebrows had been removed.
It amused me greatly, and the memory of it lurked at the back of my mind for over a decade.
I take normal peoples eyebrows on twitter – here.
And I have a gallery of Celebrities without eyebrows below.
