Planned Parenthood is a clinic specializing in birth control, venereal disease treatment, and parental advice. It first appeared in Season Nine episode, "Mr. Garrison's Fancy New Vagina", and later in the Season Sixteen episode, "Faith Hilling".
In one last effort to maintain the "Faith Hilling" meme, Kyle and Cartman took pictures in front of the Planned Parenthood clinic performing the meme. A young boy and his father walked past calling them "droll" and saying "Faith Hilling" was before their time. The Planned Parenthood Doctor then came out and taunted them by saying that his patients could "use a time machine". The final insult was from a passer-by in a car yelling, "Go back to the 90's faggots!" After these setbacks, the boys realized their favorite meme was no longer funny. Cartman stated, "The only thing that doesn't change in life is that things change."
