well went as a homicidal hockey player one year wearing a home made glove that had 4 real blades attached to it (like freddy crouger). even went up to a cop and got some candy. other then that there was the year I dug a shallow grave in the front yard put up a fake tombstone and had my friends bury me with a pager and air hose. when some kids (bought 4-6 years old) came to the door i jumped up and scared the hell out of them and their parents. best prank ever even if the parents quickly wanted to really bury me ^^
But I was kind of unlucky that last Halloween though because into the night, like an hour before 9 P.M, I scared this one little kid and his sister, and all of a sudden, the kid kicked me in the balls.
That was the worst part of the whole night, apart from being inside a hot scarecrow costume while sitting on a chair for 4 hours straight.
