39 is really nice because Ataru finally shows sme affection for Lum and they go on their first date.
73 was really funny and 156 is probably the funniest episode.

My favorite episode is 161 because Lum shrinking and she try use this situation for steal kiss on Ataru citing a story invented. This demonstrates how intelligence is Lum and knows how to do to reach their goals.
