Punching the Line: The Heart Goat

Whoever finishes this sentence with the best line wins.

There is an old South African saying:

The heart is like a goat that...

Bren:

1. pumps blood to the rest of a larger goat body, most likely made out of several smaller goats that combine, Voltron-Style, to make one Ultra-Goat.
2. ... Ummm... like, loves and stuff, I guess... you know what? Just scratch that. That's stupid. Forget I said it. The heart isn't like a goat at all.
3. has been surgically implanted into your chest.
4. loves to eat. All goats love to eat. Except that the heart doesn't really love to eat, it just loves. Really, it's a good thing that goats don't just love too, because hearts are much easier to draw.

The heart is like a goat that...
Jeph:

1. comes from a small minority of white Germanic-descended goats that push the native darker colored goats onto the rocky hill with no grass to eat...er, I don't know. There's gotta be some joke in there about the apartheid, water canons, and Nelson Mandela.
2. is like a plane that is like a soccer ball that is like a liver that is like a unicorn. Point being - South Africans are apparently terrible at analogies.
3. one cannot live without. Making every South African goat-dependent.
4. lives behind your ribs. Also, South Africa failed anatomy.

Bren- If South Africans are goat-dependent, what happens if their goat starts to fail? Can they be surgically replaced with an artificial robotic goat? Like a pacemaker, but with legs, horns, creepy devil eyes, and it eats everything?

Actual Saying: "The heart is like a goat that has to be tied up."
