Place the roast, garlic, and onion in a crock pot on high. Add the salt and pepper and a little bit of water. Cook on high until you can easily shred the pork roast with a fork. I would cook this in my crock pot (Rival) for about 5 hours.

Remove the roast and shred the meat removing as much of the fat as possible and the bone. Strain the grease in the crock pot, keeping any bits of garlic and onion left and throwing out the grease. Place the shredded meat back into the crock pot, along with the bits of garlic and onion. Pour the BBQ sauce over all until the meat is covered. Mix well. Continue cooking the pork in the crock pot for about three hours, on low. Serve the BBQ pork on Kaiser rolls, onion rolls, pocketbook buns or any speciality hamburger bun. Very Good.
