~~Most~~ many file types are just a renamed .zip

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.
I don't think "most" applies here. Text-based files, pdf, media files and most executeable files are not .zip.
