Under the hood

"Thats your problem right there", said the garage mechanic after lifting open the hood of the mans car and propping it up.
The man looked down and was surprised to see, under the hood, not an engine made of mechanical parts but a school house in some middle eastern desert country.
"Is that normally inside my car?", he asked.
"Oh yes", said the mechanic, "A lot of people don't look under the hood so they don't know whats there".
"Well can you fix it?", asked the man.
"Oh no problem", said the mechanic.
Then he held his hand over the roof of the school house and the man saw that the shadow cast by it looked like the shadow of an F-15 bomber.
Then he heard the roar of a jet engine and saw a bomb hit the roof of the school reducing it to blazing rubble and heard frantic cries from people round about.
"There", said the mechanic, lowering the hood again, "It should work now".
The man looked shaken.
"Did you have to do that?", he asked.
"Well the car wouldn't go otherwise would it?", replied the mechanic, wiping blood off his hands with an oily rag.
Then the mechanic started to talk about money and the man was eager to pay him anything just to get out of there.
"And if you have any more problems with it", the mechanic said as he was leaving, "Well you know where to come".
"Oh I don't think I'll be driving a car from now on", said the man, "I think I'll start taking a bike to work".
