Lyrics
The Chipmunks: If I start howling tonight (tonight) 'Cause someone isn't feeding me right (feeding me right) Don't let it give you a bite (bite) 'Cause this hungry canine howls with the night It's the life of a dog Digging holes in the yard Chasing cats in the street Thinking I'll never leave Yeah, under a curse And it's gonna get worse Hiding out in the ground Ending up in the pound
