Onions make me cry

Spoken: You may not know this, but I'm really a very sentimental dog.
I cry easily. Onions, for instance, always make me cry.

I'll admit I split bananas,
Take Easter eggs and make them dye.
But I never harmed an onion
So why should they make me cry?

Once I saw a salad dressing.
My face got radish, my oh my.
But I never harmed an onion
So why should they make me cry?

Potatoes I've mashed, and berries I've crushed,
I've made an artichoke, and that's not all.
I've also whipped cream, and beaten an egg.
Yes, I've even made a melon ball.

Of all the things above, I'm guilty.
If punished I would know just why.
But I never harmed an onion
So why should they make me cry?
Oh why should they make me cry?
