I have developed the world's lamest time machine...
And it seats two. We can go back to any store shelf and take as much time as needed to compare all the display dolls, sifting through the defects, to find the perfect version of that one doll to add to your collection - at decent retail prices no less. The time machine can only handle us each bringing back one doll - butterfly effect and all that.
Today I'd hunt down a Meena Fleur!
My question is... obviously, which doll are we going back to get for you?
(Obviously there are more important uses for a time machine, but humor me.)
