In the old days, when children heard thunder they used to press their belly buttons as they ran
for cover.
A rather down-at-heel doctor is on a journey. On reaching a wide plain, it begins to thunder and
as the d.ctor runs for cover, a great flash of lightening (the thunder-god) crashes' at his feet. The
thunder-god has hurt his back and can't get up again, and so begins to threaten the doctor to cure
him. The doctor pulls out a huge needle and sets about his cure.
