@thegalacticemperor,
And kudos to Stride for doing viral right. They didn't make him wear anything, or even mention stride. They just picked up the travel tab and it worked out for them.
In contrast, 3M wanted to use a viral post it prank and refused to license the pictures for a mere $2,000 because they felt like they could rip off the idea themselves for $1,000. So they copied it in a point of sale campaign instead of just harnessing the existing meme.
