Plug In Baby? What's That Then?

I don't think anyone is quite sure. Not even Matt Bellamy from what he's said in interviews:

Interviewer: "Hey, Matt, what's your plug in baby?"
Matt: "My plug in baby is my own physical body. I'm using it objectively a bit more these days. I'm not in it, I'm sort of using it. I can't explain what I mean. I make it do things now that I used to be worried about. What is it? I don't know. It's like I am my own ventriloquist. Oh, I can't remember. Help me!"
Dom: "You've said it before. You've said, 'Blah, blah, blah, and that's my plug in baby'."
Matt: "I've explained what the meaning of it is, but I don't know what it is. It's definitely myself, I think. [to Dom] Do you think we've lost it in the last few weeks? Just fucking blown it?"

Interviewer: "Now, is it true, because i was told that you said Plug in Baby was about genetically engineering puppies to live forever. Did you say that?"
Matt: "I say alot of things"

Groupie fan guy in crowd wearing an Absolution t-shirt: "What does plug in baby mean?"
Matt: "Oh shit! Ummm... It means... errr... [to Dom] Help me out. Erm It means... what does it mean? Ummm I can't remember sorry."

Matt: "It is about how we project our emotions from our innerselves into technologies around us. 'Plug In Baby' is like a made up term for 'that thing we do. I think in a generation of pretty much athanism and none spiritual times technology becomes a way of feeling connected to people"

See?

And another quote, for the hell of it:

Matt: We were all off our faces on mushrooms when we recorded Plug In Baby... There was this big field next to the recording studio filled with them. So we ate them all. I don't know what we were doing, but we all ended up naked in a jacuzzi and i went deaf in one ear from falling asleep in the sauna...

Lyrics

I've exposed your lies, baby
The underneath no big surprise
Now it's time for changing
And cleansing everything
To forget your love
My plug in baby
Crucifies my enemies
When I'm tired of giving
My plug in baby
In unbroken virgin realities
Is tired of living

Don't confuse
Baby you're gonna lose
Your own game
Change me
And replace the envying
To forget your love

My plug in baby
Crucifies my enemies
When I'm tired of giving
My plug in baby
In unbroken virgin realities
And tired of living
And I've seen your loving
Mine is gone
