How force text-only pasting in emacs?

Question

On my mac I always have an emacs buffer open and occasionally I have to copy content from PowerPoint or Word. Unfortunately, copying to the clipboard and yanking into emacs saves all the ugly formatting (and graphics) from the original document. I only want to paste in the text (and never the formatting). My current solution is to paste into TextWrangler and then repaste into emacs. What's a better way to do this?

Marginally less annoying is to use PlainClip:

Plain Clip is a tiny Mac OS X application which will remove formatting from text which is on the clipboard. It's designed as a face­less application (i.e.: no graphical user interface, with the excep­tion of the preferences win­dow), which makes it ideal for triggering it from a hotkey / launcher applications such as Spark or Launch­Bar. For users of such tools, Plain Clip offers a way to invoke it with a shell command, which makes it possible to emulate a “Cmd-V” / “Paste” keyboard shortcut after the clipboard’s content has been converted.
