Here are some other recent gems from English class:
From a third year dialogue activity. There are two pictures: 1) Ken is reading a comic book with his notebook open in front of him and his English textbook on the desk; 2) his mother comes in with cake; the comic book is peeking out from his now closed notebook and Ken is holding his English textbook upside down.
Students had to choose from a selection of responses to fill in [correct answers here]. Then students had to write original sentences to finish the skit:
Ken: Just a minute.
Mother: Here's some cake. Are you studying hard?
Ken: [Yes, of course.]
Mother: Really? What subject are you studying?
Ken: [I'm studying Japanese... I mean, English.]
Mother: What's that in your notebook?
Ken: Oh my god!
Mother: You are [a] bad boy and fool!
Ken: This is my friend.
Mother: I'm sad to hear that.
=D I was particularly impressed with the originality of the latter ("I'm sad to hear that").
Then, today the second grade students got their Unit 5 tests back. For one of the questions they had to write original sentences using the pattern: "I think that [friend's name] likes [something]." I'm not sure if these answers (emphases are mine) are so much funny as mildly disturbing....
I think that [friend's name] likes little boys.
I think that [friend's name] likes little girls.
