Terri Willis (robot Terri, not meat Terri) wrote the following lyrics:

Rock In My Shoe

Rock in my shoe
Hey, there's a rock in my shoe
I got a rock in my shoe
I should really take it out

Rock in my shoe
Don't want no rock in my shoe
No good rock in my shoe
Do I gotta take it off?

Rock in my shoe
Stupid rock in my shoe
I hate the rock in my shoe
Don't want to make an effort, but --

I should really take it out
I should really take it out
I should really take it out
Take it take it take it take it
Out!

Rock in my shoe
Hey, there's a rock in my shoe
I got a rock in my shoe
I should really take it out
