Danny DeVito On "Late Night": Dancing, Michael Douglas, And Drugs (VIDEO)

Jimmy Fallon held on to the title of "only late night host who understands how awesome 'It's Always Sunny in Philadelphia' is" last night by having Danny DeVito on as his guest to promote the fifth season of the show. DeVito danced to the "Troll Toll" song and talked about co-star Kaitlin Olson, who Fallon spoke with last week, but he also told Fallon about his early career as an actor.

While starting out in New York he met Michael Douglas who he says shared his passion for being an "herbalist" and they moved in to an apartment together for which the rent was $150 dollars a month. (You can't get a parking spot for that in Manhattan now.) He went on to discuss his days on "Taxi" and why he chose to return to television.
