Weird Al annotated

Wouldn't you know it that when I turned on the radio this am, I'd hear Weird Al Yankovich singing "I think I'm a clone now":

Isn't it strange? Feels like I'm looking in the mirror

[This would suggest opposite chirality (handedness). Not true. But it's even harder to believe that your clone would automatically achieve your current age.]

What would people say if only they knew that I was
Part of some geneticist's plan

[Your self-esteem shouldn't be dependent on what others think.]

Born to be a carbon copy man

[Carbon paper became obsolete with the electric typewriter. Bad metaphor.]

There in a petri dish late one night
They took a donor's body cell and fertilized a human
egg and so I say:

[Somatic cell nuclear transfer doesn't involve fertilization.]

I think I'm a clone now

[If you have any doubt, you can see if your karyotype matches your "master."]

There's always two of me just a hangin' around
I think I'm a clone now
'Cuz every chromosome is a hand me down

[Not entirely true. You do inherit the mitochondrial DNA from the egg cell.]

Look at the way we go out walking close together

[Would this be narcissism?]

I guess you could say I'm really beside myself
I still remember how it began
They produced a carbon copy man
Born in a science lab late one night
Without a mother or a father
Just a test tube and a womb with a view
I think I'm a clone now
There's always two of me just a hangin' around
I think I'm a clone now
'Cuz every chromosome is a hand me down
