Examples:
# To be or not to be: that is the question... To die, to sleep; to sleep: perchance to dream: ay there's the rub, for in that sleep of death what dreams may come when we have shuffled off that mortal coil, must give us pause: there's the respect that makes calamity of so long life... For who bears the whips and scorns of time..."- Hamlet, Hamlet 
# "Should I stay or should I go now? If I go there will be trouble, and if I stay there will be double, so come on and let me know. This indecisions bugging me, if you don't want me, set me free. Exactly who I'm supposed to be."- The Clash
