I thought I might as well show the picture. This was after Michelle died and Lex Luthor sent a Booster robot after Superman to kill him off and make Booster look bad. To get his revenge Booster crashes the party Lex throws, tells him that he set Lex up to lose money and steals Lex's date in front of him. Remember this rivalry when you read the Supernova/Lex sections of 52. It makes it a thousand times better and that's saying something.
