Things I've learned about leprechauns....

Leprechauns are usually seen as old men that resemble shoemakers or cobblers and are always male.

How much gold is in their pots?
One gold coin for each year of the leprechaun’s life is in the pot.

They are considered mischief-makers who delight in causing things to move or disappear from around the household of ordinary folk.
(hey, this last one is wrong........the answer to this one is not leprechauns.....it's KIDS!!)
