"The Joker's Last Laugh"
Batman and Robin trace a deluge of counterfeit money to the Gotham City National Bank and investigate the new teller, Mr. Glee. When he does not laugh at one of Batman's "super-funny" jokes, Batman decides he must be a robot and puts him out of commission. Upon analyzing the robot's clothing in the Batcave, they find some comic book inks and determine that it must have come from a printing company newly purchased by a Mr. Whiteface.
Bruce then tries to get Whiteface (in actuality the Joker) to give him counterfeit money, claiming that he needs a million dollars to cover up his embezzlement from the Wayne Foundation. In exchange for the money, he offers a document that would make Joker Vice Chairman of the National Bank.

Robin is about to be reunited with the four-colour strip from whence he came...
