I'm thinking if we could get Mr. Peabody interested, he and Sherman could take the Eayback Machine to ancient Sumer. Surely Mr. Peabody could figure out how to get better copper ingots for a good price.

But, since it seems that Mr. Peabody is forever fixing things so that they turn out the way history has recorded them for us, it is unlikely fixing the copper quality problem would be his mission. Rather, he would help write an effective customer complaint letter.

Mr. Peabody could have made editing suggestions and have told Ea, "If you want to take them, take them; if you do not want to take them, write your own lines!"

And we would see how the complaint letter was invented.
