Troilus and Cressida
And with ridiculous and awkward action, Which, slanderer, he imitation calls, He pageants us. Sometime, great Agamemnon, Thy topless deputation he puts on, And, like a strutting player, whose conceit Lies in his hamstring, and doth think it rich To hear the wooden dialogue and sound 'Twixt his stretch'd footing and the scaffoldage (1.3.149-156)
[...] At this fusty stuff The large Achilles, on his press'd bed lolling, From his deep chest laughs out a loud applause; Cries 'Excellent! 'tis Agamemnon just. Now play me Nestor; hem, and stroke thy beard, As he being drest to some oration.' (1.3.161-166)
They say all lovers swear more performance than they are able, and yet reserve an ability that they never perform, vowing more than the perfection of ten and discharging less than the tenth part of one (3.2.72-75).
