This episode marks the first appearance of Lady Elaine Fairchilde.
As Lady Aberlin arrives at the house, she pokes her head through the window next to the door. Mister Rogers invites her inside and she attempts to enter the house through the window before Mister Rogers redirects her through the door. This small amount of slapstick becomes less present as the show progresses through the decades to follow this might also be seen as controversial as her attempting to enter through the window is how robbers usually enter a house when they rob it.
Mr. Rogers changed into his sneakers at the beginning of the episode, but never changed out of them before he left.
