Oh my god, I can't believe I know exactly what they're talking about, hehe...
It's kinda like moldy fog, in my opinion.
My personal favorite part of ET is giving the ride operator fake names.
One day me, my friend, my dad, and my sister's boyfriend rode it together. Before we got on we decided our names were Peter, Dick, Woody & Rod.
No one has ever made me laugh so hard as that little alien did that day.
