One perfect moment - Impulse and Superman
From Adventures of Superman #333
Superman has received a threat involving bombs planted all around the world...
He calls for superspeed backup. Alas Wally is out, as is Jay, so Max (Who Superman has never met but knows about through Wally), and possibly with an gleefully evil little smile playing on his lips, sends Bart. Hilarity ensues...
As their race around the world continues it cemented, as if it were needed, my love for Bart's rather unique sense of the literal.
