Whether you're not at home or simply hiding from human contact, you're going to need a "please take just one candy or else" sign.

Left to their own devices, you KNOW some smartypants would take the whole bowl. 

So do these signs work? Who knows? At the very least, the kids will read them -- and making kids read on Halloween is a service to your community, no? 

Tape it to your door, or get fancy and pop it in a frame, but make sure you get your message across!
