This 1931 movie was the second in the Warner Oland series, and is the oldest to have survived. The first, Charlie Chan Carries On, along with the 3rd, 4th and 5th in the series, are lost films.
I haven't read the book, so don't know how much of Charlie's fortune-cookie wisdom was supplied by the author and how much by the screenwriters, but this film offers some great lines.
Death is a black camel that kneels unbidden at every gate.
Wages of stupidity is hunt for new job.
Mouse cannot cast shadow like elephant.
All foxes come at last to furrier's door.
Sometimes very difficult to pick up pumpkin with one finger.
Alibi have habit of disappearing like hole in water.
Even bagpipe will not speak when stomach is empty.
Way to find rabbit's residence is to turn rabbit loose and watch.
When conscience tries to speak, telephone out of order.
Even wisest man sometimes mistake bumblebee for blackberry.
Soap and water never can change perfume of billygoat.
Only very clever man can bite pie without breaking crust.
Can cut off monkey's tail, but he is still monkey.
A long life is only extra time for more troubles.
And finally my favorite . . .
Never boast about egg until after egg's birthday.
