Before I go on, I must tell you I actually fell for this. I can't believe it -- but if you stay in vacation for too long in the mountains, anything seems plausible. This is a simple trick to send one of your gullible friends out hunting for the "Snipe". There is a true snipe, but hunting one would be pointless -- they are mudbirds, and would not clash well with the palette.
Step 1: The set up
You need it to be night and in an area where animals are plenty. The suburbs are not exactly ideal, so conning your buddy into thinking you have snipes in your backyard would mean Holmes has a lost brother (or something like that). Get a flashlight, a bag, and a big stick, then send your victim out into the wilderness. It makes an even better show to set them up in an area and watch -- but we're not there yet.
Step 2: Into the fields
Tell your victim to hold the flashlight up to the bag opening "So they can see it". They should make scratching noises on the ground with the stick as to lure the snipe in. The snipe should just walk right in the bag in search for food, and you just shut the bag. The only issue is making this believable. You have to have a reason and comeback to every question, and don't shy from making something up -- that's pretty much what the entire thing's about.
Now send them off to the wilderness. It's quite funny to be there with them and point to a place to hunt, then just leave and go to bed.
