Superman #16 NM
"He only Laughs when I Hurt!" Story by John Byrne. Art by John Byrne and Karl Kesel. Superman can change the course of mighty rivers, turn mountains into dust, and stymy the destructive course of hot-liquid magma. Yet, he just can't seem to contend with the whimsical Prankster. Meanwhile, a starling discovery is made on the frozen continent of Antarctica.
