    ...as in the little poem

    A mathematician named Klein
    Thought the Möbius band was divine.
    Said he: "If you glue
    The edges of two,
    You'll get a weird bottle like mine.

    That can be found in the wiki page about the Klein bottle: http://en.wikipedia.org/wiki/Klein_bottle#Properties.

    I don't get it.

    That's NOT two Möbius bands. That is gluing the edges of one Möbius band together.
