[Clark returns to his apartment after his confrontation with Batman, where he discovered that he's Bruce Wayne. After a phone call to Lois, he notices a small bat transmitter on his cape. He looks out his window, and sees, in the distance, Batman watching through binoculars, showing that he now knows Clark is Superman. Batman waves and leaves.]
More powerful than a locomotive...and just about as subtle. [Superman steps out of the shadows, wearing a lead suit] Ooo! I'm flattered that you put on your Sunday best!
[When Superman, unaffected by Joker's kryptonite thanks to his lead suit, forces Joker to take him to Lois] I don't understand! I had it all planned so perfectly...Oh, wait! That's it!
Silly me! I forgot the ACID! [Sprays acid from his carnation onto Superman. The acid melts away half of the lead suit. Joker then throws the kryptonite at Superman's chest. Superman collapses. Joker cackles] Aw, what's the matter, Suppy? [Kicks Superman over] No more steam left in the old locomotive?
