I am surprised that nobody has mentioned two of the worst syrup wearers, Elton John and Charlton Heston. Heston's was particularly naff, a nasty ginger thing that seemed to have a life of it's own. Frank Sinatra also wore wigs for years, as does William Shatner, although his latest syrups have improved on those early plastic looking horrors that he used to wear when playing Captain Kirk.
I am glad that I was never tempted, even though it was a blow when my hair started thinning in my early 20's. The best decision that I ever made was to shave the lot off ten years ago. it has also saved me a fortune in haircuts, as well as making me feel rejuvenated, as there are so many much younger guys than me with shaved heads these days.
