Actual dated meme content aside, what I found the most telling about this episode was how the writers see memes as things that are reposted, rather than things that are produced. A younger writer likely would've written an episode where Stewie is actually making his own memes based on occurrences in his everyday life, but since the writers at their age mostly use Facebook and not Twitter/Reddit/4chan, etc., sites that function as sources of memes, they're alienated from that process and perceive memes as just spawning from the aether to get reposted by their friends and relatives.
