Sing as a two-part round, one half singing the "verse" and the other half "not yet, not yet, etc."
Black socks, they never get dirty,
The longer you wear them the stronger they get.
Sometimes I think I should wash them,
But something inside me says No, no, not yet.
Not yet, not yet, not yet...
Alternate Version
Black socks, they never get dirty,
The longer you wear them, the blacker they get.
Someday I'll probably launder them,
Something keeps telling me don't do it yet,
Not yet, not yet, not yet, not yet, not yet,
yet!
