I just saw the following episode on MeTV.

In "Goodbye, Old Paint" at the end Dubov BEGS Gilligan to give him painting lessons in exchange for the transmitter.

In the next scene we see Gilligan, the Skipper, & Professor with the transmitter but Dubov already sailed away on a raft made from his awful paintings! :lol:

So what happened to the painting lessons Gilligan was supposed to give Dubov??
