I can please him and he can please me, thank you very much!
CLARK: Really? When do I do that?
LOIS: I'm not talking about this here, with Cat listening.
CLARK: <<pouts>>
CAT: Yeah, right. Likely excuse.
CLARK: Gee, thanks.
CAT: No, I meant the part where she pleased you. If you thought anything that Lois did was pleasing, it was nothing compared to what I can do, handsome.
LOIS: Can we just have Lex blow up the DP already, so we can get rid of Cat?
PERRY:
CLARK: <<facepalm>> This is going to be a long story, isn't it?
CLARK: Now I’ve got to hunt down and blast every clown in Metropolis.
Why Metropolis is now a safer place than GC.
So, he could hook up with the cute blonde nurse in the meanwhile?
MICHELLE: Who me? Thanks. But I'm married. I do have a younger sister, Mindy, who's available.
So-so… what where we talking about again?
I don't know. Lois and Clark's sex life?
"Fighting Dirty" by Nancy. (It’s a short vignette. Easily squeezed in)

Do you happen to know the story or line which inspired it? She left that vague.
