Superman to Lex Luthor – about a box in Lex’s lair that Lex says has the missile deactivation codes. The box actually has kryptonite in it! Superman – of course – cannot see through lead and opens the lead box and Lois Lane ends up dying as a result.
More evidence that lead is bad! It can even bring down Superman!
