I lost it fighting this kid you said you weren't the best teacher in the school

I was mugged on the way to school and the mugger took everything I had

Our puppy toilet trained on it

Some aliens from outer space borrowed it so they could study how the human brain worked

I put it in a safe, but lost the combination

I loaned it to a friend, but he suddenly moved away

I didn't do it because I didn't want to add to your already heavy workload

A sudden gust of wind blew it out of my hand and I never saw it again

I was kidnapped by terrorists and they only just let me go, so I didn't have time to do it

The lights in our house went out, and I had to burn it to get enough light to see the fuse box

Another pupil fell in a lake, and I jumped in to rescue him. My homework though drowned.

I used it to fill a hole in my shoe, you wouldn't want it now

My father had a nervous breakdown and he cut it up to make paper dolls

My pet gerbils had babies, and they used it to make a nest

I didn't do it, because I didn't want the other kids in the class to look bad

I made a paper plane out of it and it got hijacked ET stopped by my house and he accidentally took it home with him
