Well one time, it was very awkaward.

My colleague went to lunch, and he was working on some website for international client.

So he left his mac unlocked, and as soon as I saw that I thought i would be cool to add click listener on body of page, and on click it opens up 100 tabs of porn. And I did that.

Before he returned from lunch, client called my boss, with wtf is happeneing with his site, and that it is constantly opening up porn.

What i didnt realize that before colleague went to lunch he contacted client to see some progress. And suprisingly I didnt know that his editor atom was automatically set up to upload website on save to dev server that client is currently looking.

We ofcourse told client it was the hackers :)

But boss wasnt that stupid.

Instant karma.
