Don't speak ill of the dead you might say

Harlan managed to get a dead gopher, and he wrapped it up in a box, and he sent it by slow mail to the comptroller at the publishing house. And he sent it over a long weekend in August, to New York. When they opened it, the gopher had ripened to a considerable degree, and they had to fumigate the entire office. Some stories say they even had to repaint it.
