    Sometimes I just unplug the nano reciever of wireless mouse from colleagues' laptop and leave them panic for sometime ☺️

    If they use Linux, you could try to alias 'ls' to something else, like 'cowsay' or 'echo bash: ls: command not found'.

    Just make sure not to alias it to 'rm - rf *', that is just mean.
