5. Shia Labeuf’s “Just Do It”
What do you mean you’ve never heard of this meme? This is unacceptable! You simply have to see the original video and all the glorious memes it helped generate. People who know a thing or two about Shia, know he can be quite eccentric (like that time when he binge-watched all of his movies with a bunch of people in a theatre), so him giving an inspirational speech in front of a green screen, and screaming “Do IT!” doesn’t sound as surprising.
