We had a guy at work that was mr know it all, always the smart ass.
So he had his F-150 transmission replaced with a NAPA transmission and at a great price.
A crew member poured 2 quarts of atf under the truck after everyone was dispatched.
At quitting time we all got to see Mr. Ass freak out, he was quick tempered, he drove back to the auto repair shop and proceeded to make a total ass of himself.
Back in the late 80's a guy at work bought a new Yamaha sport bike. It was constant brag, brag, brag. One of the maintenance guys squirted some oil in his exhaust. Once it warmed up it looked like a crop duster. He took it back to the dealer and they laughed at him.
