I was tired as hell one day driving home from work..A 24 hour (ghoster shift) once and I pulled into a Petrol station in Hendon about half way home..
Got out the car..Pissed off etc etc and this young couple approached me..
Really nice they were.
They were very politely and nervously asking me too look under their car bonnet..
I did mention that Although I was happy to look,that I was no mechanic and probably as dumb as they were.
The young man said "Please mate,just tell me where I should put the water"?
I pointed,tiredly and slightly impatiently at his radiator..
He frowned and showed me where he had put the water... IN THE ENGINE!!!
My tiredness and work stress left me at that point and looking at him and his girls helpless faces I just fell on my knees and went into an uncontrollable fit of laughter!!

After I got up,I explained where he should have put the coolant and advised him not to attempt to start the car until he called the AA.
I got in my car and laughed and laughed all the way home!! I was in fits..
The Mrs thought I was up to something,as I was laughing still as I walked through the front door!
I can still see his face now after I told him!!!
