do you ever get lonely sometimes, Joey?

So my mother and I are watching Adaptation.  If you haven't seen it, it involves a lot of orchids.

My mother suddenly laughs at something in the movie.  "The song!"

"What is it?"

She starts singing.  "Wild, wild orchids..."

Me:  "What?  Really?" 

"Yeah, it's the Stones!"

"... isn't it 'Wild Horses'?" 

Silence.  "Are you sure it's 'horses'?"  

"Wild, wild orchids couldn't drag me away?" 

My mother has said some strange things ("whales are fish, right?") but this is by far the strangest.
