剧情简介：采访拳击社途中遇到了Lois的老爸，显然两人看起来关系不怎么好。回来之后Lois有点坐立不安，问Clark你赖着不走就是想套我话是吧，你看我最讨厌拍档这样子了，因为我不会说的……

【台词片段】
LOIS: Because your partner is always there for you... whether you want him or not. Because your partner's there to share your troubles... and I don't feel like sharing. Okay... So I don't get along with my father, Big deal?
CLARK: No big deal.
