Mignon Fogarty appeared on the March 26, 2007 episode of "The Oprah Winfrey Show" as a grammar expert. She was on the show to answer a viewer question about the use of possessive apostrophes. The viewer thought a previous show should have been titled "Oprah's and Gayle's Big Adventure", but Fogarty confirmed that "Oprah and Gayle's Big Adventure" was a correct use of compound possession. She went on to discuss several other common grammar errors, including "affect vs. effect" and "who vs. whom".
