I'm sure you don't! Yours couldn't possibly be as bad as most of the (totally rubbish) Rocketshippy fanfics that already exist!!
Actaully, there was a time where I was going to write something. It went along with the whole "Pokemon Ebony & Ivory" fanfic I still haven't written. But there was one, um, episode/chapter where it was going to be full of Rocketshippy goodness.
But I've never put it down on paper.
