Dennis the Menace (1959)

S02E05 The Stock Certificate

Mr. Wilson possesses a stock certificate valued at $500, which he cleverly conceals within his phone book. When Dennis presents him with a new phone book, Mr. Wilson panics, convinced that his valuable document remains in his old book. In a frenzy, he rushes to the warehouse where discarded phone books are stored, determined to locate his previous phone book and recover the stock certificate he believes is still hidden inside.
