However, the date "3-23" might be misleading. It's likely referring to the episode's production number, which is 3-23. This number signifies that it was the 23rd episode produced in the third production block of the series. Production numbers are used to track the order of episode production, not necessarily the air date.
So, while the episode was produced in the third production block, it aired on May 3, 1957, not on March 23rd.
