a template or image gets made and then once one good joke is made from it, like Triumph_9 did in this case, it goes viral, everyone starts to make different variations. Once it's reposted. This is what a meme is :)
You’ve probably seen something similar but not this exact template. Well some templates are simply funnier than others and just have more ways you can use them or apply jokes to them.
Like the top 60 templates are the ones you see when you’re making a new meme.
