Shock-Your-Friend Laser Pointer (Working Laser) at dealexteme. Usually normal laser pointers cost about as much, but with this you get the laser that can also shock those that you give it to. It has 2 buttons, one for shock and the other for normal laser use.
For those clever cloggs that ask what the 2 buttons are for and look at you with a smartass look, just tell them that its a 2 in one laser, one with red beam the other with blue/green. That will sort them out.
Caution: this may not be suitable for kids and be aware that not everyone has a sense of humour.
