23 is my favorite, but the others are good as well.
#1...Why do we press harder on a remote control when we know the batteries are getting weak?
#2..Why do banks charge a fee on "insufficient funds" when they know there is no money in the account?

#4...Why doesn't glue stick to the bottle?
#5...Why do they use sterilized needles for death by lethal injection?
#6...Why doesn't Tarzan have a beard?
#7...Why does Superman stop bullets with his chest, but ducks when you throw a revolver at him?
#8...Why did Kamikaze pilots wear helmets?
#9...Whose idea was it to put an "S" in the word "lisp"?
#10..If people evolved from apes, why are there still apes?
#11..Why is it that no matter what color bubble bath you use the bubbles are always white?
#12..Is there ever a day that mattresses are not on sale?
#13..Why do people constantly return to the refrigerator with hopes that something new to eat will have materialized?

#16..How do those dead bugs get into those enclosed light fixtures?
#17..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?"
#18..Why is it that whenever you attempt to catch something that's falling off the table you always manage to knock something else over?
#19..In winter why do we try to keep the house as warm as it was in summer when we complained about the heat?
#20..How come you never hear father-in-law jokes?
#21..If at first you don't succeed, shouldn't you try it like your wife told you to do it?
#22..And obviously if at first you don't succeed, then don't take up sky diving!
And my FAVORITE......
#23...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.
