How about Harlequin? Harlie (Harley) for short?
From Commedia dell’Arte, maybe Arlecchino (pronounced arleh-key-no), the clown or harlequin from Commedia) or maybe Zanni (a term from Commedia for the lower class servants – who were very eccentric – I just think the name is neat sounding) in Commedia?
