"I, Mudd" is perhaps one of the most amusing episodes in this entire series so far. With the exception of Mr. Sulu, all of the central characters were present on Mudd's android-inhabited planet and we therefore got to see quite a bit more variety than is usual in the ways the actors interacted with each other. From the beginning, with McCoy backtracking after insulting Spock to Kirk's "translation" of Mudd's carefully-worded lies to Mudd and Spock's numerous entertaining asides, the way this episode flowed was uncommonly well done. I always find the humor on this series quite entertaining (especially Spock's dry tone), but this episode was just one for the record books. Mudd is a very entertaining addition to this already wonderful groups of personalities.
