It all started with this commercial, which was great.

Sandcastle tributes were made:

But this is the image that stuck:

Then the Chiefs tweeted out a SIGNED Sandcastle jersey.

So did Chiefs exec Bill Chapin:

So fans made their own Sandcastle jerseys.

In whatever color they wanted.

Even other teams fans got in on the act.

Then some Chiefs fans started to get creative.

Even non-Chiefs jerseys.

But then...

Some Chiefs fans just covered up Matt Cassel's jersey.

Some were better than others.

But why ruin your best Elvis Grbac jersey?
