I have just seen an educated person opine that Berke Breathed made up the expression “higgledy-piggledy.”
I know time and chance often combine to keep common words concealed from us. But how….?
Anyway, we have written evidence for “higgledy-piggledy” back in the 1590′s — at which time I’m fairly sure Penguin Opus was not yet waddling the earth, although I vaguely recall some gag where Bill the Cat was Bill Shakespeare.
