Shakespeare does not actually use the word "crook-pated". We do
find the following in As You Like It:
"That is another simple sin in you: to bring the ewes and the
rams together, and to offer to get your living by the copulation of
cattle; to be bawd to a bell-wether, and to betray a she-lamb of a
twelvemonth to crooked-pated, old, cuckoldly ram, out of all
reasonable match."
Touchstone is needling a shepherd who breeds sheep by suggesting
that he is essentially a pimp and is setting up his young ewes with
disgusting lecherous old rams. "Crooked-pated" is one of the terms
used to describe the old ram. "Pate" is a word for the skull or the
top of the head. The ram's head is crooked probably because it has
a set of crooked horns on it (ram's horns are curved almost in a
half-circle).
