funny (and pathetic) instructions
I'm writing my AmNovel final right now and this sentence (from the instructions) just cracks me up: "Write in complete sentences organized into coherent paragraphs."
It's so pathetic that a prof in an upper division literature course actually has to call attention to the importance of writing in complete sentences. When I saw that sentence in the mid-term instructions I thought she was being funny (or sarcastic, or something) but then I saw some of the work handed in by students and it became less funny and more sad. It's no wonder it's in the final exam instructions as well.
