Help Me With Some Leftovers (BBQ)

Long story short, I’m going home with a few pounds of leftovers today (pork, ribs, and chicken) along with some bbq sauce (but not enough) and baked beans.

I want to throw it all in a slow cooker and let it fall apart. Any of you guys have a sure-fire sauce recipe that will ensure an awesome mess of shredded meat at the end of a few hours?
