As the title of this how-to states, yes this could quite possibly be one of the meanest, if not the meanest, Christmas pranks ever. To pull this off, you'll need to booby trap a Christmas present. Not much is needed for this, just a rectangular plastic container and water. The end result will leave someone regretting picking up that Christmas gift under the tree. Yes, someone will get wet as well. Merry Christmas!!!
