Nothing says violent crime scene like a pair of bloody handprints, so have a ton of gruesome fun this Halloween or the rest of the year with these cool new Bloody Hands. This pair of realistic bloody hand clings are the perfect finishing touch to your Halloween decorations or can be used much more effectively as frightening pranks. For example, stick them on a friend's car side window, anywhere in a public bathroom, drive-thru windows or just all over your neighbor's house. This kind of macabre mischief is just good old-fashioned fun, but if the cops do show up to investigate, RUN! (via Michael Kiely)
