How can I copy/paste from mail without format?

This has been an annoying feature since I upgraded, finally bugged me enough to ask for help.

I receive a weekly newsletter that is formatted into paragraphs with multiple columns. I usually copy parts that I think my son would be interested in, then email it to him. The problem is, when I paste it into mail it retains its formatting, including the shrunken width of the original columns. When I click the text a black, rectangular box appears around it, which I have no control over.

This also happens in Safari when I copy news articles to pass on. It is extremely annoying, and I can't figure out a way to stop Lion from doing that. Switching over to text (non-html) is not an option, since I then lose the hypertext links included in the articles, as well as the images.
