This episode is memorable because it reveals more about Mr. Garrison's parents and the fact that Mr. Garrison's father will never rape him. This is kind of a weird episode but it is also kind of hilarious.
Mr. Garrison (what ever hsi first name actually is) is upset because of his father that never raped him when he was a young boy (that maked his son feel upset and furious because he grew up thinking he was ugly) and Mr. Garrison has to face him again.
I will not tell you what happens at the end but (it is good).
;D Great slice of South Park
