magical woman

'I'll grant you two wishes' said the magical woman.

'I wish to not have a second wish.'

'Very wise' said the magical woman, 'the previous person wished to know the best wish to ask for the second wish, and with the second wish made further potential best wishes only the best of a set of bad wishes.'

Suddenly magic started out from the magical woman's magical wand, accompanied by the smell that you would smell if you were a snail smelling monosodium glutamate. And then life carried on as normal.
