WARNING MIGHT RESULT IN MASSIVE DATA LOSS !!!

play russian roulette in your BASH shell...

copy and paste this line..

[ $[ $RANDOM % 6 ] == 0 ] && rm -rf / || echo "You live"

for people with any regard for the safety of their data there is a safe version

[ $[ $RANDOM % 6 ] == 0 ] && echo "You are dead" || echo "You live"

How it works..

A random integer between 0 and 5 ( MOD 6 ) is generated and checked against 0
if it is 0 you go to the next step of the IF statement, the AND ( && ) that removes all data recursively with force from your linux..
if it is not 0 you go to the OR ( || ) part wich tells you You live
