Mug - Your Bottom

You know when you pull a potato out of the ground and you can see straight away it's just not ready and is no use to anyone.

I think the same applies when some people remove their own heads from their bottoms.

They think they're clever and wise, and know what they're doing, but you can just tell.  You can tell that they should have left it right up there.

When this happens it's hard to recommend that they insert it back where it came from as it just sounds sarcastic.

So to save you the effort, point this mug at someone's newly extracted face, look at them, and tap on the words.  If they've cleared the poo from their eyes and can read they'll hopefully follow your guidance.
