Cooking in crock pots?

I actually have tonights dinner cooking in the crockpot right now! Spare ribs cooking in a blend of barbque sauce and a can of beer (idea given to me in response to a question I just asked about crockpots yesterday!). Crockpots are great. You just set it and forget it for like 8 hours while you're at work. Meats come out tender, sauces flavorful.
