There are other questions despite what is the meaning of life, here you have some samples:
Why do we press harder on a remote control when we know the batteries are getting weak?
Why do banks charge a fee on "insufficient funds" when they know there is not enough?
Why does Superman stop bullets with his chest, but ducks when you throw a revolver at him?
Why do Kamikaze pilots wear helmets?
Whose idea was it to put an "S" in the word "lisp"?
Why do people constantly return to the refrigerator with hopes that something new to eat will have materialized?
Why do we say to people who run over our feet with the shopping cart, "it's okay" instead of "that really hurt you stupid idiot!"
Why do people keep running over a string a dozen times with their vacuum cleaner, then reach down, pick it up, examine it, then put it down to give the vacuum one more chance?
Why is it that whenever you attempt to catch something that's falling off the table you always manage to knock something else over?
The statistics on sanity are that one out of every four persons is suffering from some sort of mental illness. Think of your three best friends -- if they're okay, then it's you.
