I recently rewatched the prequels with a friend and we quickly decided to count the number of scenes/lines that are used as memes and reactions.

Don't remember of the top of my head, but it was in the triple digits.

Star Wars is absolutely quotable on a minute by minute basis - if you like the meme culture around it : ^)

At this point, it's easier to count the prequel lines that haven't become memes.
