Feed Cows for a Day

It costs one dollar a day to feed a cow. Decide how many cows you want to feed and enter that number. If you want to feed 20 cows, send $20; 50 cows - $50; or feed our whole herd $500.

Human beings, who are almost unique in having the ability to learn from the experience of others, are also remarkable for their apparent disinclination to do so.
