This is an old, old joke...
So there are these two guys sitting in a bar, talking about their cars...
First guy says, "I got this new Porsche. You would not believe this car. Zero to sixty before you can even take a breath, but it handles like a dream."
Second guy says, "You should see my new Maserati. She'll get you up to sixty before you can blink, she handles tight turns like they were gentle curves, and she can stop on a dime."
From the next table, a third guy leans in. "You know," he says, "I've got a car that drives twice as fast as a Porsche and turns three times harder than a Maserati."
Well, the two guys look at each other, and then they both look at the the third guy. Finally, the first guy asks, "What the hell are you driving?"
The third takes a deep breath and says, "It's... a rental."
