"Greased Lightning"

Okay, so every once in a while I go to the library and pick up a stack of CDs to put on my iPod. Sometimes I'm searching for something specific, sometimes I just browse hoping to see something mildly interesting that I would never ever actually pay to own, but hey, if it's free, that's a different story.

This is s how I ended up with Olivia Newton-John's Greatest Hits. And just now some stupid ass Grease megamix shuffles up. A bit of it was "Greased Lightning." which I am sure I've heard more than a few times, even if I've never much paid attention to it.

Well, I paid attention to it today. Check out this bit of chorus:

Greased lightnin', go greased lightnin'
You are supreme, the chicks'll cream for greased lightnin'

Really?

But what got my attention was this:

With new pistons, plugs, and shocks, I can get off my rocks
You know that I ain't braggin', she's a real pussy wagon, greased lightnin'

Yeah, "she's a real pussy wagon." That's a line in the song. "A real pussy wagon." WTF?
