What are some creative/sneaky things you done in order to pass a class ?

Once in high school my class was assigned a project as a final (this was in grade 12). I always thought high school was a joke so I never did the assignment. Three weeks later the teacher asked me why I didn't do it and I said I did handed it in, so he looks on his desk and finds a project without a name and asked me if it was in fact mine, I lied and agreed with him and got 78% on it with a final mark of 73%.

The funny thing is that no one claimed to be the owner of the assignment and I ended up getting all the credits I needed to attend college !
