One of the tricky things about running a TV show is that you just never know how good the guest stars you cast on a weekly basis, how good they're going to be in the episode. Sometimes they surprise you in good ways and sometimes they surprise you in disappointing ways.

经营一个电视节目的棘手之处在于，你永远不知道你每周邀请的客串明星有多棒，他们在这一集里会有多棒。有时候他们会以好的方式让你惊喜，有时候他们会以令人失望的方式让你惊喜。
