If you were going to ask someone to marry you, and perhaps you already did (mazel tov!), I don’t think that your first idea of ‘how to do it’ would be Internet memes. But then, you are not the guy in this video, who uses a physical edition of PowerPoint and some block font to woo the woman of his dreams.
And it worked.
We’ll let it slide that he misused a few memes, such as the venerable Philosoraptor, because the ‘aww’ factor here is simply off the charts. I suppose, sometimes, nerds do win.
