A more accurate variation on KissmySquirrel's effort..
Two men are flying around in a helicopter, getting more and more lost,searching for their intended destination airport. The pilot says to his passenger, 'Look, there's a big building over there. I'll go and ask someone'
Hovering as close as he could the pilot shouts out to a worker in the office block, 'Where am I?'
The worker shouts back 'In a helicopter!'
With that information the pilot replies, "You must be an engineer, your answer was very accurate, concise, with no ambiguity or other information offered'
"it was also of absolutely no bloody use to me whatsoever' the pilot went on,
To which the worker responded..
"And you mate, are a typical helicopter pilot, you've screwed up, got lost, and now somehow you think its my fxxxxxg fault"!!!
