Superman: The Animated Series, Season 2

Clark Kent:
Maybe he should make time. [He goes towards Luthor's office door]

Mercy Graves:
Hey! [Bars his way] One more step and it gets ugly.

[Clark forces his way past Mercy and opens the door]

Clark Kent:
What are you trying to pull here? Where's Luthor?

Mercy Graves:
[shocked] He... he was right here! You saw him...

[Clark goes to Luthor's desk, and picks up a mug]

Clark Kent:
This coffee's ice-cold. No one's been here for a while. Well?

Mercy Graves:
[uneasy] I'm afraid you'll have to leave, Mr. Kent, right now.

Clark Kent:
Do yourself a favor, Miss Graves: call me when your lord and master shows up.
