After seeing to it that Italy’s trains ran on time, Mussolini was feeling
proud enough to order the government printing office to issue a stamp featuring
his likeness. Much to his dismay, however, postal workers began complaining
that the stamps were falling off the envelopes. Every day, layers of the stamps
filled the bottoms of their carrier bags.
Mussolini rushed to the printer and demanded to know why the highest grade of
glue hadn’t been used on his stamps. “But it was, il Duce!” the
horrified manager insisted. “We’ve looked into this unfortunate situation,
and the problem is that people are spitting on the wrong side!”
