"Fell down all fower"--Woops!

Oops; earlier I recalled that Lord Coke made King James so angry that he “fell down on all fower,” but I couldn’t find the source. Once again, my friend Carlton comes to the rescue—sort of. Turns out it was Coke who fell down, not the King. And the phrase is “fell flat on all fower.” Apparently the King was pretty chuffed, though:

After which [i.e. after Coke C.J.’s remonstrance] his majestie fell into that high indignation as the like was never knowne in him, looking and speaking fiercely with bended fist, offering to strike him etc. which the Lord Coke perceiving fell flat on all fower; humbly beseeching his majestie to take compassion on him and to pardon him, if he thought zeale had gone beyond his duty and allegience. His Majesty not herewith contented, continued his indignation. Whereupon the Lord Treasurer, the Lord Cookes unckle by marriage, kneeled downe before his Majestie and prayed him to be favorable.

18 Eng. Hist. Rev. 664, 669 (1903), reprinted in
William E. Conklin, In Defence of Fundamental Rights at 47 (1979) (Google book link)

Looks like it was I who fell down on this one, and here's hoping Speaker Pelosi stays upright.
