Note: I really did pass my quals. It was not an April fools joke. Although when the date was schedule some naughty thoughts of what I could do to my committee did occur to me.
This morning I told F1-1 that his science teacher had e-mailed me to remind him of his comprehensive exam today. He looked at me blankly. I stared back "What? she didn't tell you? You have this oral exam today, and all the science teachers in the school are going to be asking you questions and it will be 80% of your grade for this school year! You're telling me you haven't studied for this?" [put on really grim face].
I could literally see the blood draining from his face. It was quite priceless. Hey, at least someone was feeling the same thing I did. He was downright panicked. I let him steam in his skin for quite a while, but eventually could no longer stand it, and asked him if his teacher hadn't told him it was April 1st either.
The relieve on that kid's face. He was seriously sweating it, and I think he's going to school to play the same joke on a bunch of his friends, although I suspect the exam will turn in an all-topic, worth 95% of your grade kind of thing.
