You could consider using the PHP function strip_tags() which will kill all tags (both HTML and PHP tags) from the content, <b></b>'s as well 🙁
Other option is htmlspecialchars(), which will make all <b></b> tags look like <b></b> but I guess this is nog what you want either.
A 3rd solution might be using regex's like this:
$content = eregi_replace("(.)<title>(.)</title>(.*)", "\1\2\3", $content);
