Superman's Pal, Jimmy Olsen (Superman's Pal, Jimmy Olsen Vol. 2 #6)

Meanwhile, in Gotham City, the great Olsen/Batman prank war rages on. An old favorite returns to make heads or tails of just what the heck has been going on. Jimmy does some funny Fraction stuff. Batman is there, too, doing some Lieber stuff. Lex Luthor's kicking around. It's a whole thing.
