According to Wikipedia:
In mathematics, the Klein bottle is a certain non-orientable surface, i.e., a surface (a two-dimensional manifold) with no distinct “inner” and “outer” sides. Other related non-orientable objects include the Möbius strip and the real projective plane. Whereas a Möbius strip is a two dimensional surface with boundary, a Klein bottle has no boundary. (For comparison, a sphere is an orientable surface with no boundary.)
I know it’s only February, but it’s important to plan these things in advance. We’ll need at least a few hundred of these for the festivities up in the San Juans, so perhaps Chivo can start production at one of his maquiladoras so we can get them on the cheap.
Or we could drink kool-aid and lsd out of it.
