One of the in-continuity embarrassments that G-man likes:

JUSTICE LEAGUE OF AMERICA 113 (October 1974) by Len Wein, Dick Dillin and Dick Giordano.



A gigantic earthquake threatens to bring disaster on the New York coastline, and opens a gigantic fissure just off shore on the ocean floor, threatening to spread and destroy the region.

Superman takes Wonder Woman's golden lasso, dives underwater, threads a giant makeshift needle, and stitches the two sides of the fissure together, pulls it tight to close the chasm, and saves the East coast !! ( No, really !! )
