a Little Joke

Yesterday, I read a little joke that I thought it was funny, .Sso I wanted to share it with you. Then it here is the joke.
There is one was a man who works working in a certain company, who one day he buys bought a cup and there are that had some funny words on it. The words were "I want to get a raise increase salary"(我要涨工资). He always placed his cup so the has words faced side towards his boss whenever they have meetings. A month later,the boss also buys a cup with funny words that "you are fired/you get out"(滚蛋）, the other people laugh at him and say you are a brave (or foolish) man.
