Halloween haters usually just turn off their porch lights, draw the shades and ignore anyone who comes to their door, but some have a more sinister plan- to trick kids into eating a nasty treat.
You may have seen the caramel onion prank that made the rounds a few years ago, which was nasty but pretty easy to figure out before you take a bite.
But Mark Sparrow Tweeted about a much sneakier prank, so if you go to Mark's house do not eat any of his chocolate "bon bons" or you'll be sorry.
It'll soon be Halloween so time to prepare some yummy treats for the neighbourhood kids. Try dipping Brussels sprouts in chocolate for them. pic.twitter.com/HFXGA9vFSV— Mark Sparrow (@MarkGSparrow) October 24, 2016
It's a good thing most parents will only let their little trick-or-treaters eat wrapped treats, or Mark's neighbors would probably form a posse!
