It seems awfully convenient that Misha had a vial of truth serum ready to use on Dr Lane, when he didn't know there was any secret to get from him.
Ellen Lane: (held at gunpoint by Misha) Sam, I don't mean to nag, but do you do any checking on these crackpots before you sign them up as partners?!
Misha: I'm not a crackpot!
Martha Kent: No dear, trust me, you are.
Klaus Mensa: (after using his powers to kill one who betrayed him) A mind is a terrible thing to waste.
Klaus Mensa: Did you know the average human uses less then 10% of his brain? I use 98.6% of mine.
Carter Clavens: Is that why they call you Fat Head?
Klaus Mensa: I hate that name.
Constance Bailey: Miss Lane, on almost a weekly basis, you manage to dangle above the Jaws of Death.
Lois: I dangle above the Jaws of Death?
Constance Bailey: Like an hors d'oeuvre.
Clark: Lois, I want you to hear me. Every time, every time we make love, we make, love. That's the strongest lifeforce there is. Whether or not that results in another little person. To me it is creation. You fill me with life.
By the end of the series, Dean Cain and Teri Hatcher were the only two cast members to appear in every episode.

"A Mind Is a Terrible Thing to Waste" is the slogan of the United Negro College Fund, an organization founded in 1944 to provide assistance for African-Americans to attend college.
Mensa's "Dynamonics" bears a suspicious but superficial resemblance to L. Ron Hubbard's Dianetics.
