"Be A Boss" is an original song by The Chipmunks. The song is part of the ALVINNN!!! and The Chipmunks episode Who's Your Daddy and has yet to be released as part of an Alvin and the Chipmunks album. A clip of the song was included in The Alvin Show DVD (in the last 26 seconds of the episode clip).
Lyrics
The Chipmunks: I gotta grow from three foot to six two (ah ah ah ah oh ah ah oh ah) I guess I gotta, gotta, gotta put on a new suit (ah ah ah ah oh ah ah oh ah) Take the training wheels off Be a boss!
