What is a net potatoe?

His most famous blunder was when he corrected student William Figueroa's correct spelling of "potato" as "potatoe" at an elementary school spelling bee in Trenton, New Jersey, on June 15, 1992. According to his memoirs, Quayle was uncomfortable with the version he gave, but did so because he decided to trust incorrect written materials provided for the event by the school. Quayle was widely lambasted for his apparent inability to spell the word "potato". Figueroa was a guest on Late Night with David Letterman and was asked to lead the pledge of allegiance at the 1992 Democratic National Convention. The event became a lasting part of Quayle's reputation.
