Three years of digging is an absurd amount of effort for one man, and the thumbnail names the payoff, a tunnel running from his house to his shed. The open hatch and the arrow prove it exists, so now you need to see inside.

Title
It stakes three years of effort and trails off before revealing the result.
Thumbnail
It names the tunnel and shows the real open hatch as proof.
Remix this
Use this split when a project demanded serious time or effort. Put the years in the title and the finished result in the image, because the effort is what makes the payoff feel worth a click.
