ok, this is good, it incorporates a dumb blonde AND something everyone in the world could have figured out.....
Scene: Waiting Room in Anywhere USA.
Participants: Me (patiently waiting, leafing through a magazine), Receptionist (blonde, at her receiving station behind one of those glass walls), Guy (who obviously knows everything because he has a penis and is talking to the blonde....he would not have known everything if he had been talking to Me....leaning on Receptionists window ledge and gazing down at her)
G: blah blah blah, something about a car, blah blah blah blah....
R: oh! there's something wrong with my car! But I don't know what it is!
G: Well, could be your intersperlunkting meter. What kind of gas mileage do you get?
R: I don't know! I'm not good at figuring those things out!
G: Welllllll......here's what you do. The next time you go to the gas station, you know how when you're pumping gas there's this little lever under the handle of the gas nozzle?
R: no!.........gas nozzle?! (brow starts to furrow as she realizes, well, something)
G: you know...when you're pumping gas....
R: uh-huh!
G: right under where you're squeezing the handle....
R: oh!
G: there's this little piece of metal that you can push down so that the gas flows by itself...
R: no! I've never seen anything like that!
Me: (wondering wtf the flow regulator lever has to do with anything).....you know, it's not rocket science. you wait until your tanks almost empty, fill it up with gas, note how many gallons you put in, drive until you're almost empty again and divide the number of miles you drove by the number of gallons you put in last time.
R: oh!
G: (glares at me)
R: how do you know how many miles you drove?!
Me: How much longer until I'm seen?
