Lyrics
The Chipmunks:
Kids, I don't know what's wrong with these kids today
Kids, who can understand anything they say?
Kids, they are disobedient, disrespectful oafs
Noisy, crazy, sloppy, lazy, loafers
While we're on the subject
Kids, you can talk and talk 'til your face is blue
Kids, but they still do just what they want to do
Why can't they be like we were, perfect in every way?
What's the matter with kids today?
Kids, what's the devil's wrong with these kids today
Kids, who could guess that they would turn out that way?
Why do we have these children? Better to have a pet
Alvin:
You know where you stand with a pet
The Chipmunks:
What's the matter with kids, what's the matter with kids?
What's the matter with kids today!?!
