It is generally understood that the necktie is a symbol of male virility. Thus, when the Marx Brothers or the Three Stooges cut someone's tie off while the fellow is wearing it, it is a symbol of emasculation, and we laugh.
So a necktie that instantly sproings erect on command is surely the best alpha-dog symbol of all! This is why Dilbert rules!
Just don't poke out anybody's eye with that thing!
