Stephen over at they Freakonomics blog of the NY Times found a great advertising in Southern California: "There is a TV ad running here in Southern California for a pest control company. It states that “the average termite eats 24 hours a day, 7 days a week,” so your million dollar home is at risk."
I guess the top termites are probably able to eat 25-27 hrs a day. :)
Back to some seriousness:
The "Averages" are quite an interesting metric and often completely misinterpreted.
The ad above also reminds me of the famous "Average Revenue per Lead",
which pretty much says nothing without having more metrics in context.
Still a lot of people use the Average Revenue per Lead way too often.
