Somehow an <em> tag got embedded on the page

A user created a blog, but apparently I did not configure the fck editor correctly and they entered some of their own html tags which has messed up the formatting for that page.

I tried to cut the contents of the post and re-paste it into the content area using "paste as plain-text", to clear out the formatting, but it didn't work.

Somehow, an <em> tag has been embedded on the page, not just the contents of the post itself, messing up the formatting of the entire page.

How do I get rid of the <em> tag, when I do not see it in the content box?

Here is the page: http://www.scvbj.com/blog/coach

Thanks.
