I didn't think that reference was all that obscure. I think there was a reference to it in a popular NYC based tv comedy. "Buddies" or "Pals" or something like that.
Damn!
You guys are right on target.
Missed the show but that is the commercial.
People look at me like I'm speaking a strange language so I usually tell people that they are obscure references to make them feel ok about having no clue!!
I'll look for the web site. They did a long term test in Forest service vehicles, in yosemite or Yellow stone. They looked for mileage, engine wear, , maintanance, ect. It was interesting...
