What is the episode in south park where are Stan and kyle hugging each other saying i love you?

There isn't a South Park episode where Stan and Kyle hug each other and say "I love you".

While their friendship is one of the core aspects of the show, it is depicted as a strong, supportive, and sometimes antagonistic dynamic, but it doesn't typically involve romantic or overly sentimental declarations of love.

Perhaps you're thinking of a different episode or show?
