We all know of Boxer's call me senator. Here's a spoof at this
Link.
There is an Abe Lincoln precedent (not president). Lincoln the attorney was representing an army officer who was accused of assaulting an old man. Lincoln was giving his opening statement when he was interrupted by his client.
Lincoln: "There is an indictment against a soldier for assaulting an old man."
Client: "I am no soldier. I am an officer."
Lincoln, unfazed, corrected himself. "I beg your pardon. Gentlemen of the jury, there is an indictment against an officer, who is no soldier, for assaulting an old man."
