The New Adventures of Gilligan

The Disappearing Act (1x12)

:

Ginger begins to feel unappreciated, and after overhearing the Professor explaining ESP, decides to pretend she has the ability to see the future. This backfires, and the castaways decide she is a liar who cannot be trusted. Meanwhile, a trunk full of magic gear washes up on one part of the island, and a pair of escaped convicts washes up on another. Gilligan decides he wants to put on a show for everyone, while Ginger tries in vain to convince everyone that she has seen the convicts and their boat.
