以下是一些英语课堂的笑话段子，适合在英语学习的环境中分享，以增添课堂的趣味性：

Teacher: What's the plural of "mouse"?

Teacher: No, it's "mice".

Student: Oh, I thought it was "mousies".

Teacher: Can you make a sentence with the word "fascinating"?

Student: "Yes, my sister fancinates potatoes."

笑点解释：学生错误地将“fascinating”（迷人的）和“fan”（扇子）混淆，并创造出了“fancinates”这个不存在的动词，引发笑料。
