Mary Mary - The Bare Necessities

It floats up the stairs, it floats down the hall.
It floats into my bedroom, right through the wall.
It glides post my dresser, to the bedpost. I swear.
I'm looking at a ghost! Naaaaa!

There's no such thing! It's not a ghost,
because there's no such thing. No such thing.
I can't be frightened of a globby, green, glow,
'cause there's no such thing.

It plays the piano, it swings on the swing.
It does a lot considering there's no such thing.
Then it boots my computer, as quick as you please.
It floats on the keyboard. It presses some keys.
"What creature may you be?" came up on the screen.
I type in, "a human being."
