Two penguins

A man drives to a gas station and has his tank filled up. The gas pumper spots two penguins sitting in the back seat of the car. He asks the driver, "What's up with the penguins in the back seat?"

The man in the car says "I found them. I asked myself what to do with them but, I haven't had a clue."

The clerk ponders a bit then says, "You should take them to the zoo."

"Hey, that's a good idea," says the man in the car and drives away.

The next day the man with the car is back at the same gas station. The clerk sees the penguins are still in the back seat of the car.

"Hey, they're still here! I thought you were going to take them to the zoo."

"Oh, I did," says the driver, "And we had a great time! Today I am taking them to the beach."

Internal Combustion Engine

In 1860, the Società Anonima del nuova motore Barsante e Matteucci (Anonymous Society of the New Barsanti and Matteucci Engine) was formed in Florence, Italy, to manufacture internal combustion engines. On 5 Jun 1853, Father Eugenio Barsante and engineer Felice Matteucci were the first to record having designed a three-stroke gas engine that was to be commercially developed. They deposited a sealed envelope at the secretariat of the Georgofili Academy of Florence outlining their work to that date. They also held British patents. The first engine in actual operation was installed in 1856 at the Maria Antonia Railway Station in Florence. A piston was moved by atmospheric pressure after a vacuum was produced by the explosion of flammable gas inside it using an electric spark from a Rumkoff coil.«
