A couple of bloggers have flagged the uncanny similarity between one-liners by Jason Kinney, a spokesman for the anti-Obama/pro-Clinton 527 American Leadership Project, and Clinton Senate spokesperson Philippe Reines. 

Here's Kinney today: "Is it possible to quote me yawning?"

And Reines last May: "Is it possible to be quoted yawning?"

(527 groups, it probably goes without saying, aren't supposed to coordinate with the campaigns they're helping.)

To answer the question: Yes, I think it's possible--if the writer makes prudent use of brackets. Like so, "[Yawn.]" 

Just fyi...
