I wrote a story on Slashdot, and would like to copy-paste it to my company's Blogger blog, as it is very much on-purpose and will interest the readers (most of whom don't read Slashdot).

PROBLEM: I am afraid Google will strike the blog for duplicate content.

The solution is usually canonicalization: inserting this line in the story's blog page:

<link rel="canonical" href="http://slashdot.com/thestory">

This tells Google that all credits of this story goes to Slashdot, and that I am not trying to play dirty SEO tricks by replicating Slashdot's content.

But how do I insert such a line using Blogger?
If I put it in the template, it will apply to he whole blog (which would be even worse), instead of the individual story.
