Who is Theo?

Should you just let sleeping leprechauns lie? It's St. Patrick's Day in New York City when a strange man (dressed as a leprechaun!) appears in Donna and Ellie's apartment. Is he actually magical, or just a drunken fool? Either way, he somehow keeps disappearing and appearing again in different rooms! Mix in a sleep-deprived roommate, a novice policeman, numerous 911 calls, a zombie scare, a little romance and a lot of green beer, and this fast-paced new American farce will have you dying to know...Who Is Theo?
