In the ep where the Soviet Cosmonauts land on the island Gilligan overhears them talking. One cosmonaut says "We no got gun". LAter Gilligan is with Skipper and the latter says maybe the cosmonauts may have weapons or something to blow their heads off. Again, Gilligan previously heard that the osmonauts had no gun and that it was strongly implied they had no other weapons so Gilligan have told Skipper something like "Relax I overheard them say they had no gun."

In the second to last line I meant to write "Gilligan should have told Skipper...".
