A great educational video

One particular bit spoke of "PR is too complicate". That struck a memory, and I had to go and find my "Good Omens" book. Here's an extract from it.
Two Farthings = One Ha'penny
Two Ha'pennys = one penny
Three pennys= A Thrupenny bit
Two Thupences = A Sixpence
Two Sixpence = One Shilling, or Bob
Two Bob = A Florin
One Flornin and One Sixpence = Half a Crown
Four Half Crowns = Ten Bob note
Two Ten Bob Notes = One Pound (or 240 pennies)
One Pound and One Shilling = One Guinea
The British resisted decinalized currency for a long time because they thought it was too complicated.
Don't ask me why Five pee = One Shilling. I have no idear.
