Way to strip HTML from the_content ?

Problem:

Note one of the Twitter posts
Hover the “ReTweet” link – notice that the text inside of the link contains HTML

I need a way to strip all html from a post. My Google-fu is failing me and I’ve searched the codex and the plugin directory. I even tried to do it with pure PHP. I know there has to be a way to do this, I’m just not finding it. Hoping someone here knows of a method.

Here is the pure PHP method I tried within TheLoop, with zero result…

$content2strip = the_content('Read the rest of this entry »');
echo strip_tags($content2strip);

Thanks! –James
