It's a tiring job reading Tim Worstall's blog every day, as he demolishes one idiotic idea after another, a fevered lumberjack in the wide leafy Forest of Nonsense felling tree after tree with mighty blows.

Where does he find the energy?

There is particularly thick part of the forest called Ritchie. Watch our man hew away here to fine effect.

Chop. Crash.
