Et sumpto baculo, alterum illi dedi, inquiens, volo nunc pugnemus, uter nostrum femoralia ferre debet.
Source, in full
On the night of our marriage, when we were shut up in our bedroom together, I threw upon the ground a pair of breeches, and two sticks that I had provided for the purpose, and directing her to take one of the sticks, I took the other: and now, madam, I addressed her, we are to try who shall get the breeches; and whichsoever of us shall be victor this night, shall ever after wear them.
