Ever wondered why? I have. Here's the answer:

"Some scientists believe that laughing caused by tickling is a built-in reflex because even babies do it. If this is true, then you should be able to tickle yourself...but you can't, can you? Even if you try to tickle yourself in exactly the same way that another person tickles you, you don't laugh. Why is this? The information sent to your spinal cord and brain should be exactly the same. Apparently for tickling to work, the brain needs tension and surprise. When you tickle yourself, you know exactly what will happen...there is no tension or surprise. How the brain uses this information about tension and surprise is still a mystery, but there is some evidence that the cerebellum may be involved."
