An Irishman also known as O'Callihan, O'Crowley, O'Toulihan, O'Dowd, O'Houlihan, O'Hanrahan and most notably O'Hara. There are also many other variations. He owns a pub called O'Finnegans and packs massive chomps. A legend in all respects, one that will live on in Irish folklore for many generations to come. He believes in reincarnation and will be reborn as a banana slug in the next life. His brainchild is the NCBA college baseball club team, UCSC slugs in collaboration with the King. The number 7 will be forever retired for all Irish baseball players.
"Nice pitch O'malley, or should i say O'Hanrahan, let me get that chompler."
