Arnold Baumheiser is Master of None's gentle giant — Dev's towering, sweet-natured, eccentric best friend, whose oddball warmth and surprising emotional openness provide the series with much of its comic charm and unexpected tenderness. A big, goofy presence with a soft heart, Arnold is the friend who's game for anything.
His arc is mostly that of a loyal companion, but the show grants him real feeling, especially in the Italy-set second season, where his road-trip travels with Dev and his lingering feelings for an ex give him a poignant subplot. Arnold's blend of absurd comedy and disarming sincerity makes him a beloved part of the show's friend group and a reflection of its big-hearted sensibility.
Eric Wareheim — of the comedy duo Tim & Eric, and a frequent director on the series — brought a singular deadpan sweetness to Arnold.
