赖世雄中级美国英语Doing It in the Pants

Donald is in class. He raises his hand to get the teacher's attention again.

(T=teacher; D=Donald)
T: Yes, Donald. What do you want?
D: Excuse me, sir. May I go to the washroom?
T: But this is the third time in half an hour.
D: I know. But my mother made me eat a big breakfast this morning.
T: Why?
D: She said that if I eat a big breakfast, I will do better in my schoolwork.
T: But if you go to the toilet every ten minutes, you won't be able to do any work.
D: Uh... but if I don't go now, I'll do it in my pants.
T: Well, I guess if you've got to go, you've got to go.
