This is not what someone said, but what hey did...
When I bought my 2002 NSX from out of state, I had to have it smog'd before I could register it. Here in California, they put the cars on a dyno and run it at driving speed.
I take it to my favorite smog station and the technician pulls the car up and sets the front tires on the dyno rollers. I remain silent... watching out of the corner of my eye, trying not to laugh. The technician then pops the front hood, lifts it up, and stares at it for a second.
The owner of the smog station yells at him, "The engine is in the back on those."
So the technician pulls the car forward and puts the rear tires on the dyno rollers. Gets out, opens the trunk, and again, stares at it for a moment.
You had to see the look on this poor guys face... I finally stepped in (with a big grin.)
.
Priceless moment I bet.
