"When I Was His Alien" is sung by Roger in "A.T. The Abusive Terrestrial" when he feels that Steve doesn't like him anymore.
It is the sixth track on American Dad! Greatest Hits.

Lyrics
Roger: When I was his alien
And the world was young and gay
He thought I was as interesting
As teddy bears were cute
When I was his alien
Every day was Tanqueray
Every night Bacardi
And the twilight Absolut
Through the winter and the spring
We'd make a game of everything
Chowing down on dunkaroos
And watching Ricki Lake
But now he's older, breaking free
He'd rather play with boobs than me
I can't believe our special bond must break
Now I'm not his alien
What we had must finally end
I'm useless
As a car on bricks
Atop a redneck's lawn
Now I'm not his alien
Sadness is my only friend
But life...
Goes...
On.
Well that didn't solve anything. Guess I'll just go out and get hammered.
