Man, Mark Twain was holding down the early 20th century comedy scene like a champion. After he was robbed in 1908, Twain wrote a notice for all future burglars and posted it on his front door. It includes all sorts of helpful advice for those interested in thievery:
There is nothing but plated ware in this house, now and henceforth. You will find it in that brass thing in the dining-room over in the corner by the basket of kittens. If you want the basket, put the kittens in the brass thing.
The notice stayed on his front door permanently. This Twain guy really brought the LOLs, huh? Or as they said in 1908, the GAs. That stands for Guffawing Aloud. Obviously.
