W: You know I've often wondered why people laugh at the picture of a big belly businessman slipping on a banana skin and falling on his bottom. We are to feel sorry for them.

Q21：Why do many people find it funny to see someone throwing a custard pie on their boss's face?

custard pie 意为“牛奶饼”，题目问的是，为什么人们看到有人往老板脸上扔牛奶饼，会觉得很有趣？对话中也几乎是原封不动地给出了答案，那是因为我们也想做却不敢做。would like to do 是love to do 的同义替换词， dare to do 又是have courage to do 的同义替换词。

Q22：Why does the man say she would drop cups of tea at people occasionally?

relieve feelings意为缓和情绪，对话中提到，She said it relieved her feelings. 这位男生的阿姨自己亲口表示，当她被激怒时，会朝别人扔茶杯，来缓和自己的情绪，而不是如选项A 所说，to irritate them，激怒别人。所以正确答案是C。
