That was a great episode. I am half Japanese and I found the whole episode hilarious. I wasn't really tuned into at the time as me and the girl were havin a conversation and messing around, but as soon as I heard them start talking about Japanese people I had to watch, I love their exaggerated racial jokes, even when they're about my own race.
South Park is great, they make fun of every race, religion, and lifestyle. Maybe if everyone watched South Park people wouldn't be so sensitive to stereotypes and such. Just laugh about it all, good god you homos. (talking about the yuppies not you guys).
