Wrong Again, Shakespeare!

You know how I feel about owls: I either have some interest in them or pretend to have some interest in them, who the hell knows? So in HENRY VI, PART 3, Shakespeare has Warwick give a long speech about some soldiers he saw doing a half-assed job, if I may be frank, and he compares their actions to "the night owl's lazy flight." WHAT! Owls fly deftly by night, and to great purpose, I say.
