This week, Out of Office is celebrating all things ice cream. Follow along as we explore the sweet history and unexpected influences of America’s favorite dessert. On Jan. 1, 2033, Ray Alvarez plans to celebrate his 100th birthday by hosting 100 naked women in his impossibly narrow sweets shop on Avenue A, with an open invitation to the public. (A small caveat: “If anybody wants to come, [they] have to be naked,” Alvarez said.) The party will be in line with the notorious burlesque-themed soirées friends have been throwing the shop owner for years. But at 100 years old, after the party, Alvarez will take his first vacation in… forever.
