livin' in a hut, livin' in a hut, it's a put on...

OR:

Gilligan's hut, Gilligan's hut, it's a put on...

The story:

I wasn't embarrassed really, but my friend Paula and I, as adults were talking about the song one day. I told her what I thought The Who were singing... we both laughed, and afterward incorporated the phrase into our vernacular. Now we might say, "man, that guy's livin' in a hut!" to mean the person doesn't know what the hell's going on...
