Grand daddy of calorie burning sites

I've posted before about different activities to burn calories besides heading to the gym, but I recently found a more impressive site for calorie burning. This site takes into account your weight and length of activity and then lists the amount of calories you would burn in 222 different activities. While some of the options like welding or making the bed are techniques you might not think of, its interesting to take a look at simple or unique ways to spice up your workouts.
