"Chop Away at My Heart" is a song fully performed in the Milo Murphy's Law episode, "Secrets and Pies". It is sung by Zack Underwood when he was in a boy band known as the Lumberzacks (now known as Lumbermax in his absence). A slightly modified version, titled "Saw Away at My Heart" appears in the episode "Battle of the Bands". It is sung again by Zack and Baljeet Tjinder in the crossover special "The Phineas and Ferb Effect", and is also briefly heard in Phineas and Ferb the Movie: Candace Against the Universe. The film’s soundtrack also features the full uncut song for the first time.
I know you're pining
But every cloud has got a silver lining
The leaves are parting now the sun is shining
And you're in my arms so the planets are aligning
My heart is strong, like a tree!
And you belong, baby you belong to me
Without you, I'm tied to the ground
And if I fall, do I even make a sound?
Chop chop chop! Chop away at my heart!
I can feel it falling (timber!) and I will never part
I know you, you've been there from the start
So baby chop chop chop! Chop away at my heart!
And now you're grinning
When you look me in the eye, my head's spinning
If love is just a game, I think we’re winning
And we’re here right now so this feels like a beginning
I know you’re ready, you know I’m right
When I tell you my bark is always worse than my bite
When you look at me, do you see me?
Or do you only see a forest for the tree?
Na na na na, na na na na na na na (x4)
