"I bet Jake is having a bloody good laugh, wherever e is. BUMFIT. Oh come ON!"

Silas, you look a bit of an ignorant idiot for this comment.

All the sheep counting numbers of the style "yan, tan, tethera" are related to Welsh numbers, which shows they are from a Cumbrian/Brythonic language related to Welsh.

For example, "bumfit" is like the Welsh word for 15, pymtheg.

Plus the fact that variations of these sheep counting numbers appear in various 19th century publications, probably with no knowledge of each other. Are you going to tell me this Jake person is over 200 years old? Do your research first, Silas.
