The Piper claims he has been to many "solar systems". Only Earth's system is technically called the "solar system" (i.e., the system with the star Sol at its center).
Barry says they came to the Land of the Giants through a "time warp", something that has never been previously established or stated.
When the group returns after escaping the Senator's home, Betty is absent for a substantial period of time during the discussion with the Piper. Where is she?
Supposedly alien planet: The name "Timmy"
Within walking distance: the Senator's home
The Piper: I'm sorry, my little friends. I thought you might enjoy a little terpsicorian interlude.
Fitzhugh: He won't come back. A con man conned is a very shy creature. Steve: You would know, eh, Fitzhugh?
Barry: Isn't that the money you stole? Fitzhugh: "Stole" is such a harsh word. I prefer the term "business transaction".
Fitzhugh: Never trust a politician. This one would steal corn from a blind chicken.
Senator: Sorry, but today I don't have time to deal with a piccolo player, or whatever you are.
(an ever sympathetic Mark, about Barry) Mark: I think the kid's feverish or something. Are you sure you didn't eat some strange berries?
This is basically the last episode where Chipper appears, although he can be (very) briefly seen in the episode "Wild Journey."
Jonathan Harris of course played the role of Dr. Smith on Lost in Space. He seems to enjoy playing the person here to offer Fitzhugh an escape, just as many weird aliens offered Smith the chance to return home if he betrayed the others on LiS. The fact that he claims Alpha Centauri is on his route may also be a nod to that series: that was the Robinson's original destination in that show, too.
In what is either a nice continuity nod or a example of el-cheapo budgeting, the music that the senator turns on to block the Piper's music is Biff's trumpet solo from the episode "Giants and All That Jazz." Apparently his music did make it big.
Fitzhugh: A wondrous portal opened wide, as if a cavern was suddenly hollowed...
Kurt Kasznar quotes extensively and with great relish from Robert Browning's "The Pied Piper of Hamelin," a fairly famous literary work.
