Chester A. Arthur's politician buddies got pretty mad at him after he was made president (when Garfield was assassinated), cause all of a sudden he was too good for party politics. The nerve! Well, it's cause Chester had a pretty good gag going- He was totally dyin'! Jokes on them! What, they're not going to re-elect him? Oh no oh no, right? I'm guessing it was only in private that he would lean back in the oval office and snicker, "I HAZ KIDNEY DIZEAZE!!!" He also slapped a sign on the Statue of Liberty basically saying "...except for poor people, crazies, criminals and Chinese." So that's where that started.
