英語笑話:只要沒有家庭作業就可以

A unit in sex education was about to begin, and each student had to bring in a permission slip in order to take it. A boy handed in his slip and explained to the teacher, "My mom says I can take the course as long as there's no homework."學校即將開始性教育課程，每個學生都要先回去證得父母的同意，方能學習此課程。一個小男孩把他父母的同意紙條交給老師說：“我媽媽說了，只要這個課沒有家庭作業，我就可以上。”
