If you try and take her,I swear to God, I will --
Eric, Eric, trust me.
I want nothing to do withgirlfriends.
I knowwhat girlfriends do.
They make you feelthe happiest you ever felt.
Then they crawl upinside of you and...
poop on your heart.
What are youtalking about?
That's how it ends,Eric.
Girlsget you to feel for them,
make you think they'rethe best thing in the world,
and then they leave,move on to the next thing,
and you're left there,crying,
with your heartcovered in poop.
She's really smart.
And really funny.
They Poop on Your Heart
