How do I prove that sqrt(2) to the power sqrt(2) is rational ?

How about the fact that our fingers and feet skin wrinkle when exposed to water for some time, greatly increasing adhesion but decreasing sensation, wich is very helpful for slippery surfaces like rocks in water.
And btw it's the nerves that do this shit not the skin, people with paralysed hand or fingers don't have the wrinkling skin.
