Until today, Sinclair Oil was a petroleum company of which I was wholly unaware. Its logo looks like this:
How much do we all want to bet that Sinclair Oil was the inspiration for the surname of the central family on the very self-aware sitcom Dinosaurs, whose patriarch is referenced in the title of this post. I'd like to think that this was the case, especially because all of the Dinosaurs characters died in the shows finale, thus making them all prime candidates to be petroleum products today.
Also, since the subject has already been brought up, did you all realize that Jessica Walter of Arrested Development fame and soon to be of neo-90210 ignominy was the voice of the matriarch on Dinosaurs? Just try to imagine what Lucille Bluth would sound like angrily saying "Earl Sneed Sinclair" and you'll get it.
