The question " Past tense of "to wing"? " got me thinking about terms we use in the English language that derive from parts of an animal, especially verbs or verb phrases, like 'wing it' or 'hoof it'.
There are many noun and adjective phrases that use animal parts, like 'on the horns of a dilemma', so I'm more curious about verbs and verb phrases, but all entries are welcome.
(-1 to anyone who proffers 'udder despair'!)
