When Uncle Arthur comes back from his walk with Tabitha, she has on a coat. Only seconds later, Samantha places Tabitha in her playpen wearing only a dress.
This episode is set in the fifteenth century with Darrin the Bold, but in "The Return of Darrin the Bold" in season seven, the time period is the fourteenth century.
When the couples return back to the Stephenses' house after the play, it is still as light outside (as seen through both front and back doors) as when they left to go out on the town.
When Aunt Clara tries to walk through the front door, the whole front wall shakes.
Aunt Clara's lineage seems to be a bit of a mystery. In this episode, Maurice treats her as though they could be siblings, but this isn't stated. Other times it seems possible she is Endora's sister, but we are only ever told for sure that Uncle Arthur and Endora are siblings. This episode also states that Aunt Enchantra and Aunt Hagatha are sisters, but doesn't say how they are otherwise related to Samantha.
Tabitha is seen knocking the pony to the floor. However, in the next scene, without anyone picking it up, it is seen on her highchair.
When Tabitha calls the pan to her from the wall, her tray is bare. When the pan gets to her, there is a cookie on the tray.
When Samantha discovers that Darrin isn't in bed, she leaps out of bed and doesn't stop to put on her fluffy red slippers. When she runs out of the bedroom to Tabitha's room, she somehow has the slippers on.
The window Charlie Leach looks through is supposed to be in the kitchen. However, as seen from the outside, the window is too low for a window that is over the sink.
The pool area used in this episode for Florida is the same set used in episode 39, "We're in for a Bad Spell" when Darrin must push Adam Newlarkin into the pool.
During the diving in the pool scene, Samantha must twitch the "Fun Darrin" back out of the pool, because he doesn't know how to swim. In season seven however, Endora zaps up a pool into the backyard offscreen (where Darrin is standing) and he is fine.
Frank and Phyllis babysit Tabitha, even though they do not physically appear in this episode.
When we see Charlie Leach on a dirt road in "Mexico," it is actually the alleyway behind the Stephens house facade on the Screen Gems lot.
When Charlie Leach is on his way back from Mexico, the New York sign is a mixture of English and Spanish. The distance should be in kilometers, not miles.
In the scene where everything self-destructs, a chandelier hits the table. If you look closely, you will see that the table splits in half before the chandelier hits it.
The garage used when Sam catches Charlie is not the facade garage attached to the 1164 house.
This leprechaun-themed episode aired on March 17, St. Patrick's Day.
Samantha and the leprechaun fade out before they even reach the jail cell wall.
While Samantha works on her dress, Phyllis takes care of Tabitha, notwithstanding that the senior Mrs. Stephens apparently lives out of state here.
Samantha wears an Aubert dress that was also worn in episode 9.
