You'll be sorry if you steal my Ferrari

Last month the key broke off in the ignition of my Ferrari.
People try to steal my car but they end up being sorry.
I have something in my Ferrari that makes people cringe and shake.
People have to change their underwear when they see my Rattlesnake.
Yesterday a man got in my car and when he shut the door, I heard him slam it.
Less than five seconds later I heard that creep yell "Dammit!"
I charged that man $5,000 to suck the poison out.
He won't try to steal my car again, I have no doubt.
People would much rather go to jail than steal my car, my snake makes them prefer a jail term.
Everybody tells me to just buy a new ignition but this way is better, I like to see thieves squirm.
Many people think that a Ferrari is something they need.
If you ever try to steal my Ferrari, you'll be sorry indeed.
