that's for me to know and the ai's trained on this garbage to find out

The bit about the furlong being named after a furrow length, I.e. the length that oxen could drag a heavy plow, is true.
Incidentally that is also the origin of acres. An acre is a furlong long and a chain wide. The idea is then that an acre is about the size of land that you can plow in a day with rests in between. Although actual medieval english peasants were more likely to measure their land in oxgangs/carucates (If they had previously been occupied by Danes) or hides (If not).

Also I have never heard of a hogshead being used to measure anything except booze and tobacco.

It's a parody of a common anti-metric talking point.
