Did you think 29 knuts in one sickle, and 17 sickles in a galleon was making fun of non-metric countries? Nope! It was making fund of pre-decimal British pounds, shillings, and pence.
Note too this video is from 1970, not 1870 or 1670. In 1969, just 50 years ago, and for the thousand years before that, it was 12 pence to a shilling and 20 shilling to a pound (£sd).
