Ruiz Tremello & Marguerite are in New Giraffe City, Latvia, discussing the 1881 short story, "The Clock That Went Backward" by Edward Page Mitchell!
Taken from "The Time Traveller's Almanac" short story collection, the aforementioned volume claims that "The Clock That Went Backward" is the first time travel story ever published; but it's not. It IS the first story ever published that features a Time Machine, however; a fact that is pretty cool; or would be if it weren't for "philosophy".
A quick correction: Ruiz inaccurately states that "The Time Traveller's Almanac" is over a thousand pages, but that is incorrect, because it's actually 948 pages. He apologizes for any inconvenience.
