Mr. Garrison is now female (now known as Mrs. Garrison) and because of the change Mr. Slave has left him(her)it. (edit) When Mr. Garrison is getting his 'vaginaplasty' they show actual clips of a sex change operation.

In the episode commentary, Matt & Trey said they originally planned on having 4 minutes of actual surgery footage in the episode. (edit)

Gerald: Excuse me, where do you have special seating for dolphins? (edit) Gerald: I love dolphins! Ever since I was a child I dreamed of… But that has hardly bearing on what I'm here to… (Dr. Biber interrupts)
Dr. Biber: I can make you one. (edit) Sheila: Kyle, you have to accept your body the way it is!
Kyle: Why do I have to accept it when I can change it? (edit) Kyle: But all my life I felt I was black. I listen to hip-hop, I watch UPN, and I love playing basketball. (edit) Dr. Biber: With the scrotum open, I can now discard of your testicles... (edit)

This is one of the few episodes when we get to see Kyle's red "jew-fro." (edit) When the announcer calls Kyle in for a sub he says Kyle is #8 however Kyle is wearing #4 and had been the whole episode. (edit) Kyle is number 4, just like Stan in football. (edit) Kyle and the rest enter the basketball center. Three people are behind them, then in the next scene they're gone. (edit) Why would Mr. Garrison want to be a woman? He's openly expressed his misogyny many times before this episode. (edit)

In-Joke: Asspen

Look closely in the background behind Kyle the dinner table. There is a photograph of Kyle's family when they went to Aspen in the Asspen episode. (edit) Chris Rock:

When Kyle tries to talk his parents into the surgery, he holds up a picture of Chris Rock. (edit) Dr. Stanley Biber:

Dr. Stanley Biber, now retired, was a world-reknowned sex reassignment surgeon at the Mount San Rafael Hospital in Trinidad, Colorado.

However, he retired long before this episode first aired, so would it have been the real Dr. Biber? (edit) Mr. Man:

Mr. Man was also the name of a cartoon series/set of collectable figures. (edit) Misery:

When Mrs. Garrison refers to men as, "Mr. Man!", it's referring to the 1990 film version of Stephen King's Misery.

The character played by Kathy Bates frequently refers to the imprisoned author as "Mr. Man." (edit)
