Then the Wife Who Cheats agrees to elope with you, and, when she asks where the two of you should go, your reply is: "To the Moon."
I wonder how many of y'all can identify that reference. ^.^
You are referring to Jacky Gleason's famous euphemism for beating his wife Alice. Dark, but kinda funny.
I believe she's referring to "Fly me to the Moon" by Frank Sinatra and Count Basie, which was also the ending song of Evangelion.
To be perfectly honest, I just got the quote wrong. Tee hee.
Mikage's actual reply mentions outer space, not the Moon. I kinda misrecalled it -- probably because, since I watched the Sailor Moon anime, it's difficult for me not to associate the Moon with woman power and lesbian love.
