Randy Marsh has become a very hilarious character in the South Park universe. He's melodramatic about everything taking anything we may see as minor and playing it out like it's soon to be a global catastrophe. My favourite example of this is in "Make Love, Not Warcraft" when he learns that anyone playing World of Warcraft will lose their character - true to form, he gasps and yell "My Son's Playing World of Warcraft!" as though his son's life were in danger. Later in the episode, he hands Stan "the sword of a thousand truths" (from a USB storage device within the gamescape), his online character is killed and we hear dying sounds. We assume it's just a default for the characters of World of Warcraft until we see Randy making these dying sound into his microphone. Brilliant.
South Park is a fantastic programme and still one of the highest rated on Comedy Central. Really, I don't see what's not to like about it, it's humourous, it's simple and the characters have evolved well over the years. Anyone that hasn't seen it, give it a chance and anyone who has I'm certain would agree with me.
