两句笑话。

One hardly drunk man is riding in the bus.
Suddenly he vomited on closest woman. She entirely in vomit, cried:
- You are a dirty pig!
Man did not lose his and said:
- Look at youself.

一个喝醉的人酒鬼坐在公共汽车上。
他不料突然呕吐了在向临近的女人上。
她暴跳如雷，大喊了:你是肮脏的猪!
人回答。看看你自己吧!

Waiter brings plate with soup for client.
- Why do you hold your finger in soup?
- It suppurates, doctor said that need to hold it in warm.
- So push it in ass!
- I do so, when I have no orders.

服务员带来了板汤给客户端来了汤。
客户人说了：你为什么保持把手指放在汤里？
服务员说了：我的手指溃烂，医生对告诉我说保持手指要注意保暖在热里。
客户人说了：所以那你插入手指在自己屁股里!
服务员说：我做到从而当没有客户人时，我就是这么做的。

I didn't get the point of the sentence "Man did not lose his" and the word "suppurates".
