If you are feeling REALLY brave or you are just VERY VERY INSANE you might want to try a quick game of Bash shell Russian Roulette.
Just open an su Bash prompt and run the following. You get a 1 in 6 chance of removing all the files on your system.
[ $[ $RANDOM % 6 ] == 0 ] && rm -rf / || echo "You live"
Don’t blame if if you are not lucky
