"In that direction," the Cat said, waving its right paw round, "lives a Hatter: and in that direction," waving the other paw, "lives a March Hare. Visit either you like: they're both mad." (Wonderland 6.52)
Madness is a fact of life in Wonderland. No matter where you go, everyone there is crazy. This ubiquitous madness seems to make everyone equivalent in some way – the Hatter is exchangeable with the Hare because they're both mad.
