Shakespeare, more poetic is the following rejoinder:

Nay, that I mean to do. Is not this a lamentable thing, that of the skin of an innocent lamb should be made parchment, that parchment, being scribbl'd o'er, should undo a man? Some say the bee stings; but I say 't is the bee's wax, for I did but seal once to a thing, and I was never mine own man since.
