I remember a different internet. I thought the most viral stuff was a guy shoving a glass jar into his ass which then broke. And we all nervously laughed as he pulled glass out of his now pissing bloody sphincter. Or two girls puking and shitting into a cup which they drink. Or cake farts. Lemon parties. Goatse. Or just ddos random sites something something fire some space lazer ion cannon thing occupy!
Or meat spinning
Memes are as old as humanity, so Internet memes are as old as the Internet, starting ca. 1993.

Star Wars kid
Dramatic look gopher
Tron guy
Etc.
A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. The best ones are thoughts that many people can relate to and they find something funny or interesting in regular stuff.
