Tweedle Dee is a practicer of the Bahai faith.

left and right handedness ?

Two people or two groups resembling each other so closely that they are practically indistinguishable. [After Tweedledum and Tweedledee, names of two proverbial rival fiddlers, of imitative origin.] Two matters, persons, or groups that are very much alike, as in Bob says he's not voting in this election because the candidates are tweedledum and tweedledee. This term was invented by John Byrom, who in 1725 made fun of two quarreling composers, Handel and Bononcini, and said there was little difference between their music, since one went "tweedledum" and the other "tweedledee." The term gained further currency when Lewis Carroll used it for two fat little men in Through the Looking-Glass (1872). The words Tweedle-dum and Tweedle-dee make their first appearance in print in an epigram by John Byrom (1692-1763) where they are clearly nothing more than onomatopoeic representations of similar musical phrases: Some say, compar'd to Bononcini That Mynheer Handel's but a Ninny Others aver, that he to Handel Is scarcely fit to hold a Candle Strange all this Difference should be 'Twixt Tweedle-dum and Tweedle-dee! While it is clear that Byrom is the author of the epigram, it is not so clear who really wrote the Tweedle line. Thomas quotes Bartlett as follows: "The two last lines have been attributed to Swift and Pope. See Scott's edition of Swift and Duce's edition of Pope." http://www.answers.com/topic/tweedledum-and-tweedledee

1) "The Tweedle brothers never contradict each other, even when one of them, according to the rhyme, "agrees to have a battle". Rather, they complement each other's words. This fact has led Tenniel to assume that they are twins also physically, and Gardner goes so far as to claim that Carroll intended them to be enantiomorphs, i.e. three-dimensional mirror images. Evidence for these assumptions cannot be found in any of Lewis Carroll's writings."

A chiral object and its mirror image are said to be enantiomorphs. The word chirality is derived from the Greek χειρ (cheir), the hand, the most familiar chiral object; the word enantiomorph stems from the Greek εναντιος (enantios) 'opposite' and μορφη (morphe) 'form'. A non-chiral figure is called achiral or amphichiral. The helix (and by extension a spun string, a screw, a propeller, etc.) and Möbius strip are chiral three-dimensional objects. The J, L, S and Z-shaped tetrominoes of the popular video game Tetris also exhibit chirality, but only in a two-dimensional space. Many other familiar objects exhibit the same chiral symmetry of the human body: gloves, glasses, shoes, legs on a pair of pants, etc. A similar notion of chirality is considered in knot theory, as explained below. Some chiral three-dimensional objects, such as the helix, can be assigned a right or left handedness, according to the right-hand rule."
