Is there a way to copy a URL from HTML email rather than opening it in a browser?

From time to time I would like to examine the URL a spammer would like
to send me to (to figure what they are trying to make me do and how bad
it would be if I (or someone else) did click the link).

Looking at the raw message is usually useless, since the URL is hidden
in lots of base64 and/or HTML and q-p encoding.

Is there a way to copy out the URL of a link in a parsed and rendered
HTML email?
