Something to Wonder About !!!

When dog food is new and improved tasting, who tests it?
If the "black box" flight recorder is never damaged during a plane crash, why isn't the whole airplane made out of that stuff?
Who copyrighted the copyright symbol?
Can you cry under water?
Why do people say, "you've been working like a dog" when dogs just sit around all day?
Why are the numbers on a calculator and a phone reversed?
Can you get cornered in a round room?
What does OK actually mean?
Can you blow a balloon up under water?
Why is it called a "building" when it is already built?
Why is it called a TV set when there's only one?
