Wiki: "...and here the great
Earl Godwin
was proved guilty by the justice of that age of having encompassed the death of the King’s brother. Earl Godwin broke a piece of bread and held it in his hand.
‘If I am guilty,’ said the Earl, ‘may this bread choke me when I eat it!’
Then he put the bread into his mouth and swallowed it, and it choked him, and he died."
