The best thing about Kanji, is that it's easy to pun with. Tenchi, in and of itself, is littered with various puns, wordplay, and jokes, depending on various kanji and their readings. Fans of Nadesico are probably familiar with this as well. Now let's take the kanji for "Tenchi Muyo"...

(Jan. 2, 2002 - I converted the characters to html unicode entities, for simplicity. Still need Japanese fonts available on your machine to see them though (valid, unicode compliant fonts))

Take each character literally:

- Ten - sky; heavens

- Chi - ground; earth

- Mu - nothingness; infinite

- You - use; to use

天地

- Tenchi - Heaven and Earth, Top and Bottom

無用

- Muyou - Having no use; useless; unnecessary

Read in pairs, separated, it's "No need for Tenchi"

If read TOTALLY literally:

天地無用

- tenchimuyou - This end up.

Ah... such pun.
