I got pranked with this website: https://updatefaker.com/
I recently switched from manual labor to office labour and learned the hard way to lock my screen :)
In hindsight it was hilarious, but I waited for maybe 20 minutes before I got suspicious. How can I take revenge?
A very French joke: We used to use their email client and send to the whole team “Hey, I feel generous so tomorrow morning I will bring croissants for everyone. Look forward to it!”
The person would get plenty of “thank you” emails in reply and discover the trick. It was a small office so usually the person would bring the pastries. Yum!
