Rob: Somebody untie that kid!
Tony Paris (guest #4) is director/actor Jerry Paris's son.
This is generally considered one of the worst episodes in the series mainly because in the middle of rehersals the cast and crew got the news that President Kennedy was assasinated. The cast then decided to go ahead and film the episode, but without a studio audience present. The feeling was that no one would be in the mood to laugh at such a somber time. Without the feedback from the audience, the performances weren't up to the usual standards.
Laura tells Rob she booked with a place called "Dizzy Land". This has 2 allusions.
The first being to "Disneyland" with it sounding similar.
The description of "Dizzy Land" sounds like our own modern day "Chuck E. Cheese" and similar professional birthday party hosting franchises.
