Mad Sweeney is a down-on-his-luck leprechaun who is having a hard time figuring out how he lost his charm after thousands of years of acclimation to American life. He’s also the tallest leprechaun you’ll ever meet — even Shadow Moon looks up to him. Always up for a good fight, Sweeney is never deprived of one when he’s in the employ of Mr. Wednesday. So I wouldn’t recommend asking him about his pot of gold if you meet him in a bar. American Gods premieres April 30 on Starz.
