Roses aren't good symbols of love

I mean, roses only last a few weeks

And that's only if you put them in water

And they really only exist to be pretty

So that's like saying

My love for you is transitory

And based solely on appearance

But a potato

Potatoes last forever

In fact, not only will they not rot

They actually grow shit if you just leave them

That part alone makes it a good symbol

But there's more

There are so many ways to enjoy a potato

You can even make a battery with it

And that's like saying

I have many ways in which I show my love for you

And potatoes may be ugly

But they're still awesome

So that's like saying

It doesn't matter what you look like

I'll still love you
