Sometimes someone will ask 'I find it painful when I gouge out my eye with a spoon. Does anyone have a less painful way of gouging out ones eye?' and I will answer 'Perhaps don't gouge out your eye?'

And I will be told I am off topic.

Or the horse will have left, and I'll mention catching method but...I'll be off topic because the topic is about closing the barn door.

Pro tip - all outside the box thinking will look off topic at first. It's just everyone assumes they aren't thinking inside a box (really it's boxes enclosing boxes enclosing boxes - you think outside of one only to be inside a larger box).
