What's your favorite meme?

Memes have been on the internet for so long, back in the day they didn't really have a name either! Out of all the memes that have been released throughout the past few decades, which is your favorite and why? I usually didn't like most memes, but I was always a fan of "I herd u liek Mudkips" and Grumpy Cat. I also liked Rick Roll'd too but I like the song. xD Most other memes were just a bit too cringe. As for modern memes I like the Kevin James meme that started being popular about a month ago.
