YouTube series about two llamas wearing hats: Carl, who is a cheeky serial killer, and his roommate, Paul.

Carl is a cheeky serial killer, who is constantly being yelled at by his roommate, Paul. Paul dislikes Carl's sociopathic tendencies and unstoppable killings, and eventually decides to leave. The lack of Paul's presence, however, causes Carl's sanity to begin to slip away.—Julian Lilly-Howe
