Unless we're going *really* old-school I think it's "four", not "fovr".  :^)

I get a sequence beginning

sage: an[:100]
[15, 14, 5, 0, 6, 9, 22, 5, 0, 15, 14, 5, 0, 6, 15, 21, 18, 0, 6, 9,
22, 5, 0, 26, 5, 18, 15, 0, 19, 9, 24, 0, 14, 9, 14, 5, 0, 20, 23, 15,
0, 20, 23, 15, 0, 6, 9, 22, 5, 0, 26, 5, 18, 15, 0, 15, 14, 5, 0, 6,
9, 22, 5, 0, 15, 14, 5, 0, 6, 15, 21, 18, 0, 6, 9, 22, 5, 0, 26, 5,
18, 15, 0, 19, 9, 24, 0, 15, 14, 5, 0, 6, 9, 22, 5, 0, 20, 23, 15, 0]
sage: aw[:100]
'one five one four five zero six nine two two five zero one five one
four five zero six one five two '

which agrees except for the 16th term which I think should be 21
instead of 22 (u instead of v).

So looking for foxy sequences has at least one victory to its credit.
