A comedian on YouTube named Tom Mabe pranked people on Halloween by going trick-or-treating with a FAKE KID.  He dressed up a dummy in a Spider-Man costume . . . put a bag in its hand . . . and stood behind it like he was the dad.

Then as soon as people dropped candy in the bag, he picked the dummy up . . . threw it over his shoulder . . . and walked off.  So it looked like he was trying to scam them out of candy.

He also claimed the kid was DEAF when people asked him to say trick or treat.  And one guy actually knew sign language, but that one seems kind of staged.
