It’s a reference to a reddit user who would post these intricate comments with these really engaging stories that would then end with that last paragraph, which describes the events of a 1998 wrestling show where the wrestler The Undertaker threw the wrestler Mankind (https://en.m.wikipedia.org/wiki/Mankind_vs._The_Undertaker) and the type of wrestling match (https://en.m.wikipedia.org/wiki/Hell_in_a_Cell ).
The thing is, you could more or less order that for $5 as late as a year or so ago with some customizations to their other boxes. (Granted, I place no value on the cinnamon twists)
