Herbert Garrison (formerly known as Janet Garrison between his two sex changes), voiced by Trey Parker, is a recurring character in the South Park cartoon series. For the first eight seasons of the series, the character was known as Mr. Garrison but in season 9 underwent sex reassignment surgery. The character was thereafter known to the other characters as Mrs. Garrison, despite being unmarried. In the season 12 episode, "Eek, A Penis!", he undergoes yet another sex change operation. Garrison is particularly cynical, especially in comparison with the rest of South Park's adults, and he is one of the few characters to ever break the fourth wall on the show. He is also left handed.
