A strange little side quest
If Bad Ice Cream sends you down a curiosity rabbit hole, start here. Arthur Wynne published a diamond-shaped 'Word-Cross' in the New York World on December 21, 1913; the name later shifted to 'Cross-Word' and then 'crossword'. A second detail makes the picture even better: Nintendo's Donkey Kong arrived in 1981 and introduced the character first known as Jumpman, who later became Mario. That gives Bad Ice Cream a little more company than it first appears to have.
