“There, I guess King George will be able to read that!”
                                        
                                        Quoted in  "John Hancock and Bull Story" at snopes.com http://www.snopes.com/history/american/hancock.asp as one variant of traditional anecdotes of Hancock's purported exclamation at signing the United States Declaration of Independence; there are actually no contemporary or credible accounts of any of the signers declaring anything at the signing. 
Variants: 
There! John Bull can read my name without spectacles and may now double his reward of £500 for my head. That is my defiance. 
The British ministry can read that name without spectacles; let them double their reward. 
King George can read that without spectacles!
