The Prince and the Pauper: The Pauper King (s8,e21) has wrong air date.
I was checking the episodes and the first episode of the three has an incorrect air date
s3, e 21 - "The Prince and the Pauper: The Pauper King" - shows air date as 5/6/1962
The air date should be 3/4/1962.
s3, e 22 - "The Prince and the Pauper: The Merciful Law of the King" - aired: 3/18/1962
s3, e 23 - "The Prince and the Pauper: Long Live the Rightful King" - aired: 3/25/1962
