You try keeping crumbs out of a beard.
It's not easy.
And why are you blaming me for the humans in there? You're the one sticking post-it notes saying "free food, come on in!".

It is easy to go down into Hell;
Night and day, the gates of dark Death stand wide;
But to climb back again, to retrace one's steps to the upper air –
There's the rub, the task.
