Superman v2 #130
Lois: Hurry along, Clark! We don’t want to be late!
Clark: You must be joking, Lois! I… I can’t possibly wear this! I mean, if he ever finds out about this he’ll kill me!
Lois: Oh, don’t be silly! He can’t kill you! You’re Superman! Now hurry and get dressed! We’re late for the party as it is!
Clark: Oh, he can kill me all right. If anybody can, he can. And the man has absolutely no sense of humor.
