I took the liberty of copying this from an old thread.

From "A. C. Mery Talys," [A Hundred Merry Tales], 1526, #26

Of the gentleman that bare the siege board [toilet seat] on his neck.

A chandler, being a widower dwelling at Holborne Bridge in London, had a fair daughter whom a young gentleman of Davy's Inn wooed greatly to have his pleasure of her -- which, by long suit to her made, at the last granted him and 'pointed him to come upon a night to her father's house in the evening and she would convey him into her chamber secretly, which was an inner chamber within her father's chamber. So, she according to the 'pointment, all thing was performed so that he lay with her all night and made good cheer till about four o'clock in the morning -- at which time it fortuned this young gentleman fell a-coughing, which came upon him so sore that he could not refrain.

This young wench, then fearing her father that lay in the next chamber, bade him go put his head in the draught [privy] lest that her father should hear him -- which, after her counsel, rose in his shift and so did. But then, because of the savour [odor] of the draught, it caused him to cough much more and louder, that the wench's father heard him and asked of his daughter what man was that that coughed in her chamber.

She answered and said, "Nobody." But yet ever this young man coughed still more and more, whom the father hearing said: "By God's body, whore, thou liest. I will see who is there-" and rose out of his bed.

This wench, perceiving her father rising, came to the gentleman and said: "Take heed, sir, to yourself. My father cometh." This gentleman, suddenly therewith abashed, would have pulled his head out of the draught hole-- which was so very strait [tight] for his head that he pulled the siege board up therewith. And with it hanging about his neck, he ran upon the father (being an old man, gave him a great fall and bare him down and hurt his arm) and opened the doors and ran into the street with the draught board about his neck towards Davy's Inn as fast as he could.

This wench for fear ran out of her father's house and came not there a month after.
