oops, I mean, grep.

oh, i got it down to this:

date = cache_date.search('table table > td').inner_text.grep(/retrieved 
on (.+)./)


which outputs:["This is G o o g l e's cache of http://www.hello.com/ as 
retrieved on May 11, 2008 01:09:29 GMT.\n"]

How do I get rid of everything before the date?
