Years ago I sat in the McDonald's parking lot. Sign above said "Over One Billion Sold."

We (I wasn't alone, nor were we completely sober) reckoned this way:

Say 1.5 billion sold, each contain 2 oz. of cooked meat. That's 30,000,000,000 ounces of cooked meat, or 1,875,000,000 pounds of meat, or 937,500 tons (952,543.97 metric tons). Assuming that 50% of this is actually digested and not excreted, that would mean that at that time McDonald's had contributed 468,750 long tons of crap from cooked beef alone. If we assume that two pounds of...excrement will cover one square foot, that would work out to 937,500,000 square feet could be covered, or 21,522.04 acres. Using the 2 pounds per square foot, we would need 8 pounds for a cubic foot and would have 117,187,500 cubic feet, or enough shit to build a tower of shit one foot by one foot by one foot 22,194.6022727 miles (35,718.75 kilometers) high -- or about one-tenth of the way to the moon.

Remember, these figures do not include anything except cooked meat at 2 ounces per burger.

And what would the height be today, a quarter of a century later??
