The Shocking Camera. It looks like a disposable camera, but what lurks inside isn't 35mm film but enough shocking power to provide you with a bunch of laughs.
Here's how you do it: Get someone to take a "picture" with you. Look like you're monkeying around with your camera and ask your unsuspecting victim - "Dude, can you take a picture of us" and toss the poor sap the Shocking Camera. No one likes taking pictures, but we do it to be nice and we do it fast, so your victim isn't going to dilly-dally around before taking the picture. All you have to do is smile wide and enjoy the shocking show that is merely seconds from happening. Unless, of course, you're the one getting zapped. Then it's only kinda funny.
Here's another use for our Shocking Camera - I don't know about you, but I've got a couple of friends.... OK, who am I kidding, ALL of my friends... who like to take liberties with other people's cameras. You know these morons... Everyone will be having a good time at a party and this guy picks up someone's disposable camera and looks at it like the caveman probably looked at fire the first time. You can see the gears grinding inside that melon of theirs as they formulate their plan. Once they have the plan for ultimate hilarity locked into their brain, they exclaim to everyone "Hey - Check THIS out!" and typically do something very intelligent like stick the camera down the front of the their pants and snap a picture or they attempt a self-portrait while making a face that generally matches their IQ level. Just leave the Shocking Camera laying around and wait for the school-girl like screams when their plan get thwarted!
