Mr. Parker's answer about the number of times "one" appears on the dollar bill would be incorrect if referring to a current Federal Reserve Note, where the number "1" in numeral or spelled-out form appears a total of 16 times: eight times each in both numeral form and spelled out. However, at the time this was filmed, the dollar bill in circulation was a Silver Certificate, where the numeral appears 9 times and spelled out 16 times for a total of 25.
The number of times ONE appears on the $1 bill in numerical or written form was ACCURATE at 25 ! They would have been using a 1934 $1 silver certificate . The currency at the time.
The song Ralph identifies as "Take Me Back To Sorrento" written by Ernesto DiQuista in 1898 is actually "Come Back To Sorrento" written by Ernesto De Curtis in 1902.
When Ralph guesses "Shuffle Off to Buffalo" as the song Norton is playing, he mentions that it was written for "a picture called 42nd Street back in 1932". 42nd Street (1933) was released in 1933, not 1932.
