This inspires the boys to come up with new ideas to revamp their show . </P> <P> Ms. Pearl is the Home Economics teacher . She speaks with a soft, gentle voice and does her job well, although she appears to believe in old - fashioned gender roles, namely by having all the girls on her course, despite a couple having applied for wood shop class, and by teaching her class ways to find, manipulate and marry rich men . She is good with chat up lines (as seen in "Tweek vs. Craig"). She also dates Richard Adler, and mentioned she wanted to sleep with him . He refused because he was still mourning the death of his fiancée . </P> <P> PC Principal is the current principal of South Park Elementary, replacing Principal Victoria in the show's nineteenth season .

The episode also showed that Principal lives in a fraternity house with other similar, violent, college - age men that is a few houses down the street from Randy and Sharon Marsh's house . It is later implied that he is part of a larger conspiracy involving online ads . Once he discovers this conspiracy, however, he turns against the ads to defend humanity from their intolerance .

He has been the principal ever since . </P> <P> Mr. Slave, voiced by John Hansen, is the homosexual lover of Mr. Garrison up until the episode "Mr. Garrison's Fancy New Vagina" when he breaks up with Garrison after Mr. Garrison had a sex change .

In many episodes, he says little else . </P>
