I quite liked this episode, but as others have pointed out, not for its wonderfully logical and coherent storyline. I enjoyed it for the same reasons Qutluch mentioned, basically. Their whole scene in Janeway's quarters where he's trying to convince her of his awesomeness cracks me up. Janeway's line "I beat out a single-celled organism?" - and her delivery - is still funny to me. Also her response to Q's tattoo comment "mine's bigger": "Not big enough" - followed by that face. I tend to like it when the crew gets out of their uniforms for once.
