That cannot be done as the leprechauns are a very private people, as you may have noticed as you've most likely never met one.
It was first brought to my attention on a bus ride many years ago when I became trapped in the luggage compartment as I attempted to escape my guardian of the moment. While in the luggage compartment I met a family of leprechauns and as I was still a wee lad myself (I was 8 or 9) they thought I was one of them and gave me books as a parting gift as we traveled the countryside.
One evening as we were making our way towards Auckland, (yes the bus traveled under water) a leprechaun sneezed and a page from a book flew out into the ocean and was gobbled up by a fish. The other leprechauns became enraged and fed the naughty sneezing leprechaun to the fish.
It turned out that in the olden days in Egypt, there were leprechauns that would sneeze as a way to tell the overseers at the pyramid building sites, that there were traitors within the ranks of leprechauns. This is why you don't find leprechauns sneezing, they know it is a sign of treason!
At any rate, due to that sad incident with the leprechaun, I was taught to never betray the secrets of the leprechauns.
Years later, my sister studied Egyptian history and in talks I learned that she had unearthed the truth about the leprechauns as well. For having told me this, she has never found a pot of gold.
So, I am afraid, I cannot divulge any more of my secrets and sources.
