I'm surprised nobody has mentioned this one:


Just sit right back and you'll hear a tale, a tale of a fateful trip, That started from this tropic port, aboard this tiny ship. The mate was a mighty sailin' man, the Skipper brave and sure. Five passengers set sail that day for a three hour tour. A three hour tour.

The weather started getting rough, the tiny ship was tossed. If not for the courage of the fearless crew, the Minnow would be lost. The Minnow would be lost. The ship set ground on the shore of this uncharted desert isle,
with Gilligan, the Skipper too, the Millionaire
and his wife, the movie star, the Professor
and Mary Ann, here on Gilligan's Isle.
