The Joker: His Greatest Jokes #[nn]

When Batman and Robin are summoned to Washington D.C. to meet FBI Director G. Henry Mover, the meeting takes a deadly turn—The Joker opens fire, leaving the F.B.I. chief wounded. With a grin and a taunt, the Clown Prince of Crime vanishes into the open road, launching a cross-country spree of chaos and crime, daring Batman to follow.

In this imagined tale from Alfred’s private journal, the Second Batman and Robin face a chilling new threat: the Son of the Joker, wielding his father’s signature chaos with a twisted legacy of his own. As the duo confronts a mind game spun from the Joker’s darkest laughs, even the shadows seem to mock their resolve.

In "This One'll Kill You, Batman!", the Joker escapes custody with a deadly twist: he doses Batman with a laughing virus that will kill him in three days unless an antidote is found. With time running out and the only man who could make the cure already dead, Batman must race against the clock—while the Joker watches from the shadows, laughing all the way.
