What is 56th Base?
Where you go in a time machine and find the past version of you and fuck yourself whether you like it or not, either way, one of you wanted it
Past version of you: I think i might go to bed
Present version that timetravelled : mmm hello me, sex time
Past version : this is too crazy im being shafted by ...myself!
Present version: i think i'll call this 56th base
