So relaxing...
`brew install asciiquarium`

I used to work in a Tech Support department where everybody was constantly pranking each other.

In one of the iterations of such events one of the guys actually forked the source of a login page, in one instance of the app that was running in a VM, and edited the code so it would redirect the user to a lemon party'ish website.

It was quite an upgrade to the old M.O. where people would just email themselves messages with seemingly bureaucratic call to actions containing hyperlinks to the same lemon party'ish websites.

And the most direct approach, which is to type those directly into one's browser if the laptop is left unattended & unlocked due to a trip to the toilet.
