Best for the 30-second laugh.
For when you need to test a pointless site on a coworker:
Eelslap — drag your mouse to slap a man with a fish. The most committed-to-the-bit website on the internet. The author has never explained why. We've never asked.
Hacker Typer — type any keys, look like you're hacking the Pentagon. Built in 2011 by Duiker101, still works exactly the same in 2026.
Bury Me With My Money — men falling, voice intoning the title. That's the entire site. Has been the entire site for over a decade. The voice still sounds the same.
Make Everything OK — a single button. Press it. A progress bar tells you everything is being made OK. Nothing actually happens. The honesty is the whole joke.
Patience Is A Virtue — tells you, factually, that patience is a virtue, then does nothing else for as long as you're willing to wait.
These five reliably deliver the pointless register inside thirty seconds.
