Gilligan's Island Radio???

[Eric H]

I liked episode where the radio gets thrown in the Ocean, swallowed by A Fish and they find it because they can hear it playing inside the Fish they just caught, just like it would happen in real life.

Back in those days I remember Carbon Zinc cell batteries lasting about 20 minutes under normal use (I may exaggerate a little).

Then there's the one where Gilligan's Tooth Filling becomes a radio...
