Naturally, it's turned into a meme, because the internet can't help itself. This is why Twitter exists.
Also, kudos to Trump for actually taking some time to prepare for once, since he's notorious for hating stuff like that — he doesn't attend briefings, didn't practice for the presidential debates...
Even Trump himself has admitted this.
At the 2017 Conservative Political Action Conference (CPAC), recalling the speech he gave at the 2011 CPAC, he stated,
I walked the stage on CPAC — I'll never forget it, really. I had very little notes and even less preparation. So when you have practically no notes and no preparation and you leave and everyone was thrilled, I said, 'I think I like this business.'
"I had very little notes and even less preparation" is Trump in a nutshell.
But, it looks like he did have a few notes this time around.
Thankfully for all of us, he was captured reviewing them, and now we have so many glorious memes.
