Action Comics #102

Mxyztplk is back to make Superman's life a misery. On this occasion he overhears Superman saying that Aladdin's magic lamp might be too much even for he to handle. Mxyztplk researches the lamp and causes a giant version to appear on the street, labelled 'Property of Aladdin DO NOT TOUCH'. Inevitably curiosity gets the better of some people and when touched Mxyztplk appears as the genie and starts granting wishes. Superman and Lois get him to agree to three wishes, which include voluntarily pronouncing his own name backwards, which sends him back to his own dimension.
