WordPress Plugin to display RSS in posts?

Is there a WordPress plugin which can show RSS feeds in posts? I am not seeing one and when I search on Google it shows pulling rss and doing auto blogging which is not what I want. I simply want my WordPress RSS feed to be like a button or something in each WordPress post.

I found some plugins which enabled it in a widget but my client does not want that.

Thanks for your quick help :).

You mean… just adding a link to the RSS feed in each post?

Pretty much but I want it in the footer of the posts. Looking for a plugin so the client can turn it on / off as will.
