A while back I wrote a post highlighting a rambling Andy Kaufman monologue from an episode of Taxi, and arguing that Kaufman hadn't rehearsed. The commenters, along with more viewings of some of Kaufman's own routines, convinced me I was wrong: that's just the way Kaufman liked to deliver his lines. But I was still wondering why Kaufman was doing his own thing in that particular episode, whereas in most of the episodes he delivered his lines in a more disciplined way. Well, I've figured it out; I incorrectly assumed that the episode was directed by the show's regular director, James Burrows, but it turns out Burrows was away that week and the episode was the work of one of Paramount's contract directors, Jeff Chambers. Apparently Burrows leaned on Kaufman to tone down his Foreign Man schtick and say the lines without all the halting and hesitating, while a guest director let him do what he wanted (or at least couldn't stop him, whereas Burrows could). Another minor TV-geek mystery solved, and one of the few cases where the identity of the director makes a tangible, clearly-visible difference in the tone of a sitcom.
