Just Saying HiG 20

At the beginning of the third day, there will be a meeting between the KKK and the Drow Elves. At the conclusion of this meeting, you'll get your final two buddies, Cartman and Kyle. Now you can just cycle through each buddy and fart on them - Butters, Kenny, Jimmy, Stan, Cartman, and Kyle. I tried doing this during the story before I could actually use Cartman and Kyle, and it didn't work. They must be active as your buddy when you fart on them for this to count.
