Crocodiles tears

Crocodiles really do produce tears. Because, while eating, they swallow too much air, which gets in touch with lachrymal glands (glands that produce tears) and forces tears to flow. But it’s not actually crying. The term “Crocodile tears”  (and equivalents in many other languages) refers to a false, insincere display of emotion, such as a hypocrite crying fake tears of grief.
