Color of My Eyes

As I went to subscribe to EETimes Europe, one form question did give me huge surprise. They were interested in color of my eyes.

I am not sure what surprises me more - their question or explanation for it. They say: “Normally you are asked to sign a registration card to validate your free subscription, but this is not possible on a web page. Instead we ask a qualifying question that must be answered:”.

At what time did naming of color became substitute for signature? Have I overslept that moment?

P.S. If someone is interested, they are brown. :)

P.P.S. Don’t steal my identity now!
