A customer parks a brand new car outside a mechanic shop and goes inside.
Mechanic: Good day to you, sir.
Customer: I wish it was, I really do.
Mechanic: And what seems to be the problem?
Customer: My new car is all messed up. The engine is missing.
Mechanic: What do you have out there?
Customer: It’s one of those new fiats. And the engine is missing.
Mechanic: Well it’s either that or maybe it is in the back.
Customer: In the trunk?
Mechanic: Yeah, just think about it. If it was missing you wouldn’t be able to drive at all, right?
Customer: Yeah, you’re right.
Mechanic: Let’s go see.
They go out to look at the car. Customer pops the trunk.
Mechanic: There you go. It was there all the time. Nothing to worry about.
Customer: I’ll be damned. Where is the trunk then?
Mechanic: Well it’s at the front.
Customer: That’s going to be confusing now.
Mechanic: I believe you'll figure it out. Anything else?
Customer: Also the gas mileage. It isn’t what they advertised. It’s supposed to go about 40 miles per gallon.
Mechanic: How much you’re getting?
Customer: About 10.
Mechanic: Yeah that is slightly off. Let me take a look.
Mechanic (looking): Ah there we go, your hand brake was engaged.
Customer: Wow, is that something bad?
Mechanic: Only if you do it. Now let me put it down for you.
Customer: So every time when I want to save money I put it down?
Mechanic: Well that’s one way of looking at it, but here my advice; you leave it down and never touch it again as long as you live.
Customer: Got it. So my car is ready?
Mechanic: I don’t see why not, it is brand new car. The only thing it is missing is the wipers.
Customer: Oh, that was me, I only use them when it’s raining, make them last longer.
Mechanic: Smart man. In that case you’re good to go.
Customer: How much do I owe you?
Mechanic: It’s free. I'll tel you what, I want you to use that money to buy a book, ok. It’s called common sense for beginners. Will you do that for me.
Customer: I will. Good bye.
Mechanic: Bye.
