Yes, I’ve seen that viral email, and no, this isn’t about that.
So I looked at the Onion’s horoscope today. It’s not my birthday, but that’s not the point:
Now I hadn’t a clue what the ‘Gerber baby’ is/was, so I interpreted this one jaw-dropping (but to me also very funny) way. A quick google later, and I realise that The Onion probably had a different interpretation in mind. Still funny, but less Hannibal Lector.
It’s babies! Gerber baby food is made out of BABIES! They’re making baby food out of babies! Next thing they’ll be breeding them like cattle for food. You gotta tell them. You gotta tell them!
Alternate interpretation - if you have ever eaten Gerber baby food, you would know it tastes like sh*t (most baby food does). Ergo, the food probably killed the Gerber baby!
I’m guessing that when the OP found out Gerber was a brand of baby food, she(?) assumed the joke was that the pureed food was so bad or disgusting that the baby either died from eating it, or starved to death from not wanting to eat it.
Soylent babies was my interpretation. Somehow I didn’t conceive that baby food would taste like crap, thereby killing the Gerber baby, simply because I don’t eat baby food.
