Rain dance in Gilligan's Island

Some Native stereotyping from a popular 1960s TV show:

"Gilligan's Island": Water, Water Everywhere (TV Episode 1965)
Episode aired 2 January 1965The castaways desperately try to find a new water source as they have completely exhausted their current water supply.Gilligan’s Island Transcript

Mrs. Howell wears a headband with a feather in it. Her dress looks vaguely native American, but she has accessorized it with a broach and pearls.

MRS HOWELL
I can't understand it, Thurston. All that nonsense about a divining rod to bring water.

MR HOWELL (O.S.)
Yes, I know. Totally unscientific.

MRS HOWELL
Are you ready?

Mr. Howell enters dressed in a Cherokee ceremonial headdress.

MR HOWELL
Yes, any time you are, my dear. One, two, three.

The Howells perform a "rain dance."

HOWELLS
Ha!

Mr. Howell and Mrs. Howell look to the sky.

MR HOWELL
Rain!

Mr. Howell looks at his dry palm and then back up at the sky.

MR HOWELL (cont'd)
You're not listening.

MRS HOWELL
I don't understand it. It worked last year in Yellowstone Park for the Cherokees.

Comment:  I don't remember the line about the Cherokees. The show may have eliminated it during filming.

The fact that it's in the script makes the stereotyping worse. Clearly the writers didn't know the difference between Plains and Cherokee Indians, or anything.
