Leprechaun at Large in Cincinnati

The other day a man found a stranger in his car pantless. When questioned by the police the pantless man claims a Leprechaun let him in. Strangely enough, when you find the end of the rainbow and steal the gold, Leprechauns take your pants, intoxicate you, and stow you away in a stranger's car for punishment. Everyone knows that.... This Leprechaun must be caught!
