Wrapping comments in quotation marks

I would like to wrap my comments in quotation marks. I’ve tried this:

“<?php comment_text(); ?>”

But comment_text(); contains paragraph tags, so the closing quotation mark appears on a new line, rather than at the end of the last sentence in the comment, where I would like it.

Making paragraph tags display as inline elements solves this problem, but of course at the expense of formatting within the comment. Ditto with doing this, which I guess ultimately does the same thing:

“<?php $commentBody = get_comment_text(); print $commentBody; ?>”

Is there any way to append a ” at the end of each comment, before the final </p> tag?

Thanks in advance for your time.
