Name an expression that begins with "First?

Answer 1

From Shakespeare's "Henry VI":

---------------
DICK.
The first thing we do, let's kill all the lawyers.

JACK CADE.
Nay, that I mean to do. Is not this a lamentable thing, that of the skin of an innocent lamb should be made parchment? that parchment, being scribbled o'er, should undo a man? Some say the bee stings: but I say, 'tis the bee's wax; for I did but seal once to a thing, and I was never mine own man since.- How now! who's there?
---------------

Despite what the ignorant believe, Shakespeare is not anti-lawyer, he's anti-anarchy. Dick and Jack are revolutionaries intent on overthrowing the monarchy.
