I don't think anyone would expect this pair to look so much alike... but they do. And when such a bizarre epiphany comes about, one simply has to share it. The likeness is undeniable. Even Snoop's hairstyle, which isn't too similar in this particular photo, does correspond more closely when he's sporting his strange but frequently occurring old lady curls.
It's also important to note similarities outside of physical ones. For example, Voltaire and Snoop Dogg both use pen/stage names. Snoop was born Cordozar Calvin Broadus, and Voltaire accordingly was François-Marie Arouet. What does it mean? Probably nothing... but it's worth mentioning. Also, Voltaire was known for his satirical style... and who can't detect the sarcasm in Snoop's "izzle" language. He actually had a short lived show called Doggy Fizzle Televizzle. I think Voltaire would have thought that was pretty funny. I know I do.
