I don't think it's all that funny
Buddy, my life's filled with constant pain
When my heart begins a-thumpin'
It always wants to make an escape, ho-oh-oh-oh
When animated, it looks silly, ho-oh-oh
Worth a chuckle or guffaw
But the feelin' when that vital organ
Launches itself out ain't great, hate my cartoon heart

Cartoon heart, cartoon heart (oh-oh-oh-ho-oh-oh-oh-oh)
Cartoon heart, cartoon heart (ooh-ooh-ooh, ho-oh-oh)
Cartoon heart, cartoon heart (whoa-oh-oh-oh-yeah-eh, hey)

It was pretty scary, first time someone got flirty
Didn't foresee that, hey
Not the part of me that should burst free
Hard to believe but it's still true
Straight out of a Looney Tune, this cartoon heart

Cartoon heart, cartoon heart (oh-oh-oh-ho-oh-oh-oh-oh-oh-ooh)
Cartoon heart, cartoon heart (oh-oh-ooh-ho-oh-oh)
Cartoon heart, cartoon heart (ah-ah-ah-ah-ah)
Thumpin' right out of the frame, hate my cartoon heart

Are my ribs a-crackin'? Well, maybe
I haven't got this checked
So worried I'd get dismissed outright
As a liar, that ain't right, stupid cartoon heart

Cartoon heart, cartoon heart (oh-oh-oh-ho-oh-oh-oh-oh-oh-ooh)
Cartoon heart, cartoon heart (oh-oh-oh-ho-oh-oh, pain)
Cartoon heart, cartoon heart (ah-ah-ah-ah-ah)
Why can't it just stay in place? Hate my cartoon heart
