Why...

... do we press harder on a remote control when we know the
batteries are getting weak?

... does someone believe you when you say there are four billion
stars, but check when you say the paint is wet?

... doesn't Tarzan have a beard?

... do Kamikaze pilots wear helmets?

... is there an "S" in the word "lisp"?

... if people evolved from apes, are there still apes?

... is it that no matter what color bubble bath you use the
bubbles are always white?

... is there never a day that mattresses are not on sale?

... do people constantly return to the refrigerator with hopes
that something new to eat will have materialized?

... 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?

... is it that no plastic bag will open from the end on your
first try?

... when we are in the supermarket and someone rams our ankle with a
shopping cart then apologizes for doing so, why do we say, "It's all
right." Well, it isn't all right, so why don't we say, "That hurt you stupid
idiot?"

Thanks to Becca for sending this one to me. Some of these hit just a little to close to home! :)
