facebook content, and the classic request for more of it.

facebook content.
1. I Just made my facebook account, and I could use a little more cowbell.

2. Glad to see your facebook content, but I could have used a little more cowbell.

3. About the content on your facebook page fellas, I'm telling ya, your gonna want that cowbell!

4. If you got a fever to learn more about your long lost pal and the only prescription is more facebook content, ask them to explore the space and lay down the cowbell with you! Right here, right now, with us, together...
