Danny DeVito is returning to series television for the first time since his days as boss of Taxi's Sunshine Cab Company with a regular gig on FX's It's Always Sunny In Philadelphia. DeVito will appear in all 10 episodes of the show's second season (premiering in June), although he'll shoot all of his scenes within 10 to 15 days — roughly half of the show's overall production schedule. That noise you hear is Vincent D'Onofrio calling his agent.
