The only thing I couldn't understand was why it was just poison oak and not a snake or something.

我唯一不明白的是为什么它只是毒橡树而不是蛇之类的东西。

I hardly think so. You be sure and say hello to all the mosquitoes, bees, bears, snakes, possums, poison oak, oh, and last, but not least, teenagers with guitars.

我不要，你们一定要跟以下生物问好，蚊子，蜜蜂，熊，蛇，负鼠，毒葛，最后，也是最重要的是玩吉他的少男少女们。

I had gotten beggar lice and twigs and stuff all over me, inside my clothes and shoes and all, and then I happened to look around and I had my hand right on a bunch of poison oak.

我身上到处都是乞丐虱子和树枝之类的东西，在我的衣服和鞋子里等等，然后我碰巧环顾四周，我的手就在一束毒橡树上。
