People for the Ethical Treatment of Animals (PETA) parodies Jamie Lynn Spears' current pregnancy in a new commercial that urges the spaying and neutering of pets. In it, a teenage girl is told by her parents to "get out there and nail everything you can... if it's got a pulse, you should be wrapped around it."
When the girl recoils in horror, asking what would happen if she should become pregnant, they respond with a shrug, "You should pop out all the kids you want. We can leave them in the shelter, dump them in the street, whatever."
Although the clip doesn't actually mention Spears by name, the similarity in appearance to her character in Zoey 101 makes the reference clear.
