After being a scientist for many years I can now confirm that Zac Efron is made out of cheese, Yes CHEESE.
After losing his farm he turned into a schizophrenic madman that would not go within 20 yards of a candle wick. After he bought back one of the cows he milked it to make cheese out of that and replace the arm that had been bitten of by his girl friend "Vanessa Hudgens" after a wild night of passion two weeks prior.
The second reason to proove my theory was when he was performing in "High School (Bloody) Musical" The performance was so cheesy that this could not possibly a human acting, if that was a human acting I would have thrown my self of a bloody cliff by now to save my self from the cheese.
No human could act like that and not be made out of 99% lactose solution.
