from the Paranormal Database:
John Kelleher captured a leprechaun under a rock near the summit of Mushera mountain, and agreed only to let the creature go if it gave him a purse of coins. The little man told Kelleher that if he dug where he stood, he would find the purse. Kelleher let the leprechaun go, stuck a stick in the ground to mark the position and went home to find a shovel. Returning a short time later, the man found hundreds of identical sticks all stuck in the earth around the area. (the date of this is unkown)
