Random real word generator needed

I'm looking for an app or script that will generate lists of random real (i.e. are in the English dictionary) words. Ideally I'd like to be able to control the word length but otherwise there's no other criteria.

I've checked the MAS and Macupdate as well as a general search of the Internet, but these turned up nothing but random text generators for creating passwords or gibberish filler text (such as lorem ipsum).

Of course there are plenty of Windoze apps but I don't have Parallels or Boot Camp so those are out.

thanks!

@ dmi: that's an unusual (but effective) solution. I'm familiar with Terminal but not with scripting. Is there a way to add to this script that will (a) select only words of a given length (say 5 characters) and (b) list more than one word at a time (say list 10 words)?

Thanks!

@ dmi: I didn't see your edit when I asked about word length and # of words.

Many thanks for creating this script. It is perfect for my use.

I don't see any functional difference between these two but they both work fine.

perl -MList::Util=shuffle -e 'print ((shuffle grep{length==6}<>)[0..9])' /usr/share/dict/words

perl -MList::Util=shuffle -le 'print for (shuffle grep{chomp;length==5}<>)[0..9]' /usr/share/dict/words

With best regards for a good weekend!
