Big Man on a Little Stick - S1-E22
Continuity mistake: As the Professor sends Duke off, he gives the island's position as 110° Latitude, 10° Longitude. In "X Marks the Spot" (S1: E: 19), the position is given as 140° Latitude, 10° Longitude.

Factual error: In the beginning of the episode, Gilligan is fishing. He catches a freshwater trout in a 'saltwater' lagoon.





Chosen answer: It looks like a mistake to me I see it when the Professor is put into a trance, but it is not there later.
