A man goes into a pet shop and starts looking at the monkeys. The first one he comes to is $20, but the next one along is $50. So he says to the store owner "how come this monkey is so expensive?"
The store owner says "well that monkey is a very clever monkey, it is a LAME and can tear down engines, balance blades etc".
The man is very impressed and keeps walking down the line of monkeys until he comes to a monkey with a $100 price tag. "Wow" says the man, this one is really expensive. "ah yes" says the store owner, "that one is a check in counter monkey, a very clever monkey that can meet and greet passengers and even complete load sheets".
Now the man is deeply impressed until he comes to the last cage with a fat, grumpy looking monkey with a $1000 price tag. "A thousand dollars for a chimp? what the hell can he do" the man enquires.
"nobody knows" says the store owner, "he just sits on his arse drinking beer all day and playing with himself... but his papers say that he is a helicopter pilot....."
