Stan and kyle have always been the best of friends. They did everything together. They played video games, get pissed at cartman together...that was until one day while Stan and kenny were in the park they both saw kyle kissing wendy testaburger, Stan's crush...once she left kyle saw the two of them he walks over to them and can tell that stan is pissed.

Kyle: I can explain everything stan. This is not what it looks like trying to get him to calm down
