Go Go Go

A man in a Porsche 911 stops at a stoplight and a guy on a scooter pulls up next to him.
The guy on the scooter leans over and takes an admiring look at the inside of the Porsche and tells the driver that he has a really hot car.
Well, the light turned green so the driver of the Porsche decides to show off and peels out and leaves the guy on the scooter in the dust.
Then, all of a sudden, he sees the scooter zip on past him.
So, being a little cocky, the Porsche driver floors it again and blows past the guy on the scooter.
A few seconds later, he again sees the scooter zip on past him.
So now he's a little irate as well as a little miffed that that scooter keeps passing him.
He really floors it until he is going over 100 mph.
He thinks that there would be no way that scooter could catch him now, but, there in the rear view mirror and sees that scooter starting to catch up.
That's It... He decides to find out what that scooter really is.
He slams down hard on his brakes.
The scooter crashes into the rear of the Porsche.
After the dust settled, the Porsche driver sees the scooter driver lying in the road and goes over to him and asks how he could go as fast as the Porsche on such a little wimpy scooter...
The dying man replied, "I can't really, but my suspenders were caught on your side mirror...."
