Steff's line "That was quite a jolt, Freak" is repeated six times (not counting the tag after the credits).
Steff's oft-repeated line, "That was quite a jolt, Freak" was a parody of the line, "That was quite a jolt, Jeff" from Ed Wood's Plan 9 From Outer Space, delivered by Wood's wife Norma McCarty.
The episode is a parody of the classic H. G. Wells novel, 'The Island of Dr. Moreau.'
