PHP Text / Sentence / Word Generator Script?

Anyone know of a good php text / sentence / word generator script? I've found some for perl, but would really like php. I've found one php sentence generator here:

Scroll down to the bottom of the page to see the php sentence generator script. It works well, but the sentences it spits out are very repetitive in structure. Anyone know of any better scripts? Let me know. Thanks.
