A friend bought a brand new Geo. We had to listen every day to his MPG report. Always, 40, 42, 41 MPG.
So, we started adding gas to his tank, a little at a time. the geo started getting 50 then 55 then 60 MPG.
We kept adding gas to the tank, it got up to 75, then 85 then 90 MPG.
We decided to wean him off the gas, so we added less and less. it dropped to 75, then 65 then 60.
Even less gas added, and it dropped to 45 then we quit adding gas.
Of course, we couldnt quit, we started syphoning. When it hit 25, he took it in for a tune up.
LMAO!!! That is one of the best I've ever heard!
