I saw a few playsets at Hot Topic that had two dolls of variousl Happy Tree Friends characters, one regular and one sliced up and dead. (With the exception of a doll who my memory recognises as Flippy, who has a regular and insane version.) I assumed it was toys making fun of a children's show I never saw. Then I saw the Happy Tree Friends audibles on Yahoo! Messenger, which were in no way violent, with the exception of the Flippy audible, who growls. I assumed Flippy was growling because he's a bear. Then, I saw a submission on the South Park guide that mentioned Happy Tree Friends, and I just had to look it up on Wikipedia. I then realized I was wrong, those playsets came from their own show. I decided to watch some of it. (The first one I saw was "Nuttin' Wrong With Candy")
And so, I became a fan after a while. How did you begin watching? And, if you remember, what episode did you see first?
