Insert content into yield

I have a feeling that the answer to this question is staring me in the face somewhere. Apologies if its obvious.

On the blog I’ve built with Middleman, I want to write a helper that will add a "join my mailing list"call-to-action after the first two paragraphs of an article. I can’t figure out how to insert this content once the yield is called? Is it a matter of skipping the yield, grabbing the body of the article and explicitly calling it on its own through content_for? Curious what the best practice would be in this scenario.

Thanks in advance for any suggestions and/or advice.

Answered my own question. Article.body.

Not quite sure what you were after but it seems like you need to resource to the locals?

Thank you. It was an even simpler fix than that. I just needed to call article.body and then insert a partial into the template. I was making my job harder than it needed to be. Thanks again for the input.
