Students in my editing classes may submit errors that they find in the print media and get extra credit. I encourage such finds in newspapers, magazines and books. I accept other professionally produced writing, however.
Today, someone brought in a spelling mistake. That's typical. The place where the error appeared was not: on a Snapple bottle cap. The cap reads as follows:
Real Fact #127
A humminbird's heart beats 1,400 times a minute.

The missing "g" is there on the Web version. I suppose it's less expensive to fix that than to recall thousands of bottle caps.
