I love the "There is you, there is me, there is no us" line (or somethint to that effect) when Perry first partnered them up. It's in such contrast to her "feeling" him wake up after her father "cures" him in "Home is Where the Hurt Is."
And then there's Perry's line about Clark walking on water for Lois, or he'd die trying.
Sorry I can't be more specific about episode titles. Maybe someone else can offer that info.
