"Tempus Fugitive" arguably has the most well-known CMOF of the series with this exchange:
Lois: If you wanna kill Superman, I don't know why you're going to Smallville or 1966. Tempus: She doesn't know yet. Oh, this is good. This is really good. Um, Lois, did you know that, in the future, you're revered at the same level as Superman? Why there are books about you, statues, an interactive game. You're even a breakfast cereal. Lois: Really? Tempus: Yes. But, as much as everybody loves you, there is one question that keeps coming up: "How dumb was she?" Here, I'll show you what I mean. Look. (puts on glasses) I'm Clark Kent. (takes glasses off) No, I'm Superman. (puts glasses back on) Mild-mannered reporter. (takes glasses back off) Superhero. Hello! Duh! Clark Kent is Superman! Ha, ha, ha. Well, that was worth the whole trip. To actually meet the most galactically stupid woman who ever lived.
From "Operation Blackout"
Clark Kent: Gee, Lois, if you were thirsty, all you had to do was say something. Lois Lane: Clark, this isn't just any beer! Clark Kent: I know. "It goes with sun and good times!"
From "Meet John Doe"
Malcom: Gotta go. Gonna jump to my death soon. Buh-bye.
