Just by chance, Melanie's "Brand New Key" has been afflicting me as an earworm today. I'm far from fond of the song, but it gets my vote for the most double entendre loaded song to ever reach #1 on the US pop charts. And she claims to have been unaware of the sexual innuendo when she was writing it. Yeah, right....

"Brand New Key"

I rode my bicycle past your window last night
I roller skated to your door at daylight
It almost seems like you're avoiding me
I'm okay alone, but you got something I need

(Chorus)
Well, I got a brand new pair of roller skates
You got a brand new key
I think that we should get together and try them out you see
I been looking around awhile
You got something for me
Oh! I got a brand new pair of roller skates
You got a brand new key

I ride my bike, I roller skate, don't drive no car
Don't go too fast, but I go pretty far
For somebody who don't drive
I been all around the world
Some people say, I done all right for a girl

(Repeat Chorus)

I asked your mother if you were at home
She said, yes .. but you weren't alone
Oh, sometimes I think that you're avoiding me
I'm okay alone, but you've got something I need

(Repeat Chorus)
