One evening, a beautiful 17 year old daughter came home, feeling slightly worried.

Her dad noticed that something was wrong, and repeatedly asked her if there was anything she wanted to talk about.

Finally, the daughter revealed what had been bothering her.  Her new boyfriend had said something that she hadn’t quite understood.  

“He said that I have a beautiful chassis, lovely airbags and a fantastic bumper,” the 17-year-old said.

Her dad leaned back in his chair and took a few deep breaths to keep his anger at bay.  

He said to his daughter, “You tell your boyfriend that if he opens your bonnet and tries to check your oil with his dipstick, then I will tighten his nuts so hard that his headlights will pop out and he’ll start leaking out of his exhaust pipe!
