Snudge

"Snudge, one that lurks under a Bed, to watch an opportunity to Rob the House."
B. E., A new dictionary of the terms ancient and modern of the canting crew (1700).

"So, thinks I, I'll go and search them rooms. Upstairs the hall was dark, but I found the duke's room, and started to paw around it with my hands; but I recollected it wouldn't be much like the king to let anybody else take care of that money but his own self; so then I went to his room and begun to paw around there. But I see I couldn't do nothing without a candle, and I dasn't light one, of course. So I judged I'd got to do the other thing--lay for them and eavesdrop. About that time I hears their footsteps coming, and was going to skip under the bed; I reached for it, but it wasn't where I thought it would be; but I touched the curtain that hid Mary Jane's frocks, so I jumped in behind that and snuggled in amongst the gowns, and stood there perfectly still. They came in and shut the door; and the first thing the duke done was to get down and look under the bed. Then I was glad I hadn't found the bed when I wanted it. And yet, you know, it's kind of natural to hide under the bed when you are up to anything private."

Mark Twain, Huckleberry Finn (1884).
