A boy had reached four without giving up the habit of sucking
his thumb, though his mother tried everything from bribery
to reasoning to painting it with pepper sauce to discourage
the habit.

Finally she tried threats, warning her son that, "If you don't
stop sucking your thumb, your stomach is going to blow up like
a balloon!"

Later that day, walking in the park, mother and son saw a
pregnant woman sitting on a bench. The four-year-old watched
her for a minute, before saying, "Uh-oh... I know what YOU'VE
been doing."
