Although it may sound like this is one of the stranger ideas you've seen in a long time, trust me, it really IS great.
1. It's best to start the day before you want to make this.
2. Make up a single recipe for the Butt Kickin' Cocoa Rub.
3. Rinse, then dry the chicken, then cut off any additional fat or skin.
4. Coat the chicken with a little oil then with the Cocoa Rub, place in a plastic bag, and set in the refrigerator.
Although this is my preferred method, in a pinch, you can get away with putting the rub on the chicken just prior to placing it o the grill.
5. The next day, Soak the chips in water for at least one hour. Then, make up 1 recipe for Butt Kickin' Root Beer Mop.

Start the grill:
6. While the grill is getting ready, place the soaked wood chips in pouch made from aluminum foil.
7. Place the pouch on the grill then the chicken, and put the lid on. Regulate the heat so that you don't have too much under the chicken or it will burn.
8. Turn the chicken after about 15 minutes, and baste with the mop.
9. As you're cooking, be sure to rotate the chicken on the grill to keep it from burning.
10. Continue smokin and cookin' for about 1 1/2 hours, or, until the chicken is done.
