Tom Baker has never been funnier as the Doctor, flat out deciding to take a break from the quest and go fishing. Mary Tamm gets to play a double role - no wait, a TRIPLE role - in the form of Unsexy Romana, an android duplicate, and a caged up princess. Also, K9 gets stuck on a canoe and hilarity ensures. This story is also home to That beast from The Androids of Tara, clearly the best and most convincing Doctor Who villain ever conceived.
