Mr. Garrison, The 3rd Grade Teacher

Herbert Garrison (known as Janet Garrison between his two sex changes) is a recurring character in the South Park cartoon series. He is voiced by Trey Parker. 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 (back to a man). 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. Read more on Last.fm.
