Cubital Tunnel Syndrome - What's That? - Brandon P. Donnelly, MD
The "funny bone" refers to the ulnar nerve as it passes through the cubital tunnel over the medial epicondyle (bony bump) on the inside of the elbow. Because the nerve lies directly against the bone with little padding, hitting this area compresses the nerve, causing a sharp, tingling, or shock-like pain down to the fingers
...they call it the funny bone but I never experienced it doing anything funny.

Liberals are like a "Slinky". Totally useless, but somehow ya can't help but smile when you see one tumble down a flight of stairs!
