Mothers, please don't beat your babies

Allison and I were just chillin out tonight, listening to the Happy Feet soundtrack while we cleaned up her room, when she suddenly says: "This is the one where they don't beat baby girls."

That made me stop for a second. I was trying to remember a place in the movie where the penguins beat up the baby penguins. I know there was a part where the dad was worried that he'd drop an egg. But I don't remember them actually beating one of the babies.

"When do they beat the babies?" I ask.

"No they don't beat the baby girls I said."

I crinkled up my forehead trying to think what the hell movie she could possibly be talking about when I realized which song was playing. It was Nicole Kidman singing the Prince song, "Kiss." And that's when I realized what the first line of the song might sound like to the unfamiliar brain of a three-year-old: "You don't have to be rich to be my pearl," becomes:

"You don't have to beat baby girls."

Now my question is this: Is it weird that Allison understood that as a perfectly innocuous line?
