In a small bowl, mix paprika, garlic powder, onion powder, brown sugar, salt, and pepper.
Rub the spice mix evenly over the pork shoulder.
Place the pork in the crock pot. Pour in the chicken broth and BBQ sauce.
Cover and cook on low for 8 hours or high for 4-5 hours, until the pork is tender and easy to shred.
Remove pork from crock pot, shred with two forks, and return it to the juices.
Serve on buns or as desired.
