Sourmath.com

Sourmath.com, formerly sourpatch.org (and also known as nobrain.dk) is a shock site that was registered sometime in 2007.

The site's main page displays a flash video showing 3 elderly men having sex in a bathtub, alongside them showering and cleaning each other. The edited video is cut out into certain parts of the footage while a cover of the theme tune of The Andy Griffith Show plays in the background,. There is also large text underneath the video that says "HELLO!".

Mirror sites
There is a site called "nobrain.dk", which is a notable mirror that contains a script that will cause your browser tab to bounce around on the desktop. Although not effective, the only way to close the website is to open Task Manager. To end the process, navigate to the program using the arrow keys, and press Enter or ALT+E. Otherwise, you will get a dialog message: "HELLO! LOOKS LIKE SOMEONE F****ED YOU! 1! 2! 3! GO TO NO BRAIN.DK 4! 5!".

The video is also known as Canadian Tea Party, which is known for being a slang term and is called that by many reaction videos. The original owner moved the website to another domain called sourmath.org in 2018, and it's still active to this day.

The site gained a bunch of popularity because of a bunch of mirrors with a domain that misleads the people for weird reasons, there is even a Yahoo question of it, in which the person asks the website might be suspicious or not, this website also spread across Reddit.
