Probably not the best prank idea...

Oh dear this is what happens when I lurk aroound tumblr for too long. Basically on tumblr there's an awesome blog called imagineyourotp.tumblr.com which has lots of ideas for otps for fanfics, art or just something nice to imagine.

Anyhow in this pic Rainbow Dash has gotten Twilight to play Slender at her place, unfortunatly Dash, being the best girlfriend in Equestria has chosen to play a prank on her during this.
