Nothing Is Perfect

The computer in Dan's car is helping him reach his hotel. (D=Dan; C=computer)
D : OK, computer, how do we get there?
C : Go one block and take a left.
D : That looks easy. (He turns right.)
C : Left! I said "left," you idiot!
D : Sorry! Wow, you don't have to get so angry.
C : I'm sorry. I guess I'm just having a bad day.
D : A bad day? You're a computer! How can you have a bad day?
C : Well, I think I've got a virus.
D : Ha! And I thought computers could never be wrong.

丹汽车里的电脑正引导他前往旅馆。
丹:好吧, 电脑先生, 我们怎么去呢?
电脑:往前走过一个街区, 然后左转。
丹:好像很简单。(他往右转。)
电脑:左转!我说“左转”, 你这个白痴!
丹:对不起嘛!哇, 你也用不着这么生气啊。
电脑:抱歉。我想大概是我今天过得不顺利吧。
丹:不顺利?你是部电脑, 怎么会过得不顺利呢?
电脑:呃, 我想我被病毒感染了。
丹:哈!我还以为电脑永远不会出错呢。
