The 6 Marauders (Snape, Lily and the other 4)

We all know that the Sorting Hat has only made 7 mistakes in sorting people into houses and that Snape was one of the 7.
What if the sorting hat hadn't made that mistake and Snape was put in Gryffindor.
This story has a lot of pranks.

P.S. I don't own Harry Potter. I only own the characters which I create.

I have made a few big changes to the actual plot line. So it might change the turn of events.
