17 - I didnt want to make the other students feel bad. Your excuse for not bringing it in is that it is so good that the other students would feel bad that theirs was not as good as yours.
12 - I noticed it got dark outside and I spent the night worrying why. You can try this one a number of ways such as, Water started falling from the sky and I was worried the sky was leaking, and The sun went missing in the evening and I was on the phone all night with the milk carton. 6 - I lost my dog, so I had to eat it myself. The old gag is that your dog ate it, so this is a play on that. 7 - A psychic told me I would lose a leg if I did my homework last night.
19 - My Internet went down, your teacher will reply with how you could have printed it off and brought it in, but you then reply with, Oh no, that wasnt the problem, without the Internet I had no way of copying the answers. These excuses are not going to get you out of being in trouble, but if you are in trouble anyway, then you may as well enjoy it. Some of the lines are going to make your fellow students laugh, so there is always a silver lining to every situation.
This works great if someone has already handed in the work and had it marked because you can claim you lent your work to them and have not had it back yet.
4 - I had no food in the house, your teacher will reply, How or why would that stop you doing your homework? To which you reply, I cant work on an empty stomach, can you?
You could always say you were just being cheeky and that you will hand it in tomorrow. Read all news.
