The woman's answer? A gerbil.
Because of that anti-gay urban legend about Richard Gere putting gerbils into his anus for sexual pleasure and having to go to the emergency room to have them removed.
Iowa City and the University of Iowa have a history with the urban myth of "gerbils as sex toys for gay men" when the now-former "Campus Review" editor-in-chief (and current Cedar County Attorney) Jeff Renander created an anti-gay "Gerbil Quilt" in 1990 to mock the UI's gay students, as well as the AIDS Quilt.
The answer was not a correct answer and the woman was sent back to her family with feigned shame. I did actually watch the end of that particular program and her family ended up winning the game.
