Give Me A Place To Stand And I Can Pump All The Gas In The World

I usually get gas at my local ARCO station since it's cheapest there. Last time I was at the pump I noticed a sign that read "I Save, Therefore I ARCO - ARCOmedes, Famous Greek Mathematician."

There's a lot going on here.  First, the pun on "I think, therefore I am." Weird to see it at a gas station.  But then the pun on Archimedes, which is even better.  Then noting ARCOmedes is a famous Greek mathematician.  First, it's a made-up name.  Second, either people have heard of Archimedes or not--if they haven't, you can say he's a famous anything, who cares?  Finally, for an ad trying so hard, anyone who might be impressed with its erudition would have to know that the original quotation is from Descartes.
