Bull in a China Shop? Peace, man!

I read a report of an experiment recently where they put a real bull in a real china shop.

What they found was that the bull carefully AVOIDED all shelving and china. VERY little damage done.

So they put another bull in the shop and together they both tried to avoid the china and shelving. Again, VERY little damage done.

Finally, they put a third bull in the shop and, in perfect harmony with diseconomies of scale, only now was there any damage as the bulls needed to avoid each other as much as the china and shelving!

This was on Mythbusters! So where did the bull in a china shop scare story come from I wonder?
