How to take a mirror picture with an iphone?

I have a really hard time doing it, any advice?

So… Next time you take a ***, wipe your *** on the mirror BEFORE wiping with toilet paper (this is needed to get the full effect). After that, run your phone under cold water to get the sepia effect (it makes you look good in a mirror). Then take a picture with one finger in each nostril. Hope this helps.
