For english I always came up with some long winded surreal story which goes nowhere
Well.. I was about to do my homework, but I diddnt have a pen. So I went to the shop to buy a pen but on the way I was ambushed by no less than thirty mountain gorillas. They wanted my wallet but I only had enough for the pen. I told them I needed it but they diddn't believe me

I ran, luckily mountain goriallas don't run too fast. I ran into the port and hid in a submarine.... However, The submarine left shortly after I got on board. I had escaped the gorillas but now had bigger problems. It wasn't long until the crew of the ship found me. They took me to the captain and he introduced himself as "Captain Gring". He was a pirate who talked with a lisp. He said "What are you doing aboard my thubmarine? Nobody thows away on my thip!!" he decided to lock me in a cabin and leave me there. That was a month ago (At this point the teacher will comment that they set the homework a week ago. Say "I haven't got to the time machine yet")...
I can't be bothered to write any more but you get the idea.
