Once I get started on party ideas, some of my ideas are horrid and others would work pretty well! When planning a party, it's great to get creative, and not as good to get too creative. Having some sense to step back and consider likely outcomes helps. For example, you might think "why not try having a severed human hand lying on the buffet table, at the end in the corner?" Don't. People will freak out, call the cops - your party will be pretty much ruined.
Instead, put napkins there! Perfect touch.
