Really? I mean, it's reasonable that you might enjoy the episode (I think the first half is awesome), but the singing boil being a classic? Prepare to have your opinion attacked, friend.
No, my mistake. I was speaking too nonchalantly when I used the word "classic". I don't mean classic as in "pure genius episode that ranks up there with Godfellas and The Late Phillip J. Fry". I meant "classic" as in "that's pretty funny". Sorry for the confusion - I tend to use that word more liberally than I should!
