A long title denotes that this has to be at least mildly entertaining, at the very least to myself.
Firstly, get incredibly bored. Seriously. Boredom is Key.
Next, choose any person you know, preferably one that you know very well.
Finishing that, make up a difficult-to-truthfully-answer question that has many options. An example would be:
If you could only save yourself and one other person in your class from a devastating and ultimately fatal fire, who would that person be?
After that, answer that question truthfully to yourself, or to everyone around you if you are feeling brave/suicidal.
Then, step into the shoes of your previously chosen person(who you ought to know at least rather well), and think profoundly about how that person would answer that question.
Congratulations, you have amused yourself.
Failing that, you have just wasted several minutes of your life.
