Holiday Party Festivity Levels

Level I: 

     Your guests are conversing quietly, nibbling at their hors d'oerves,
     and sipping their drinks. Later, some of the gather by the piano to
     sing carols while others admire the ornaments on your tree. 

Level II: 

     Your guests are talking loudly, wolfing hors d'oerves, and drinking
     from the bottles. Some people gather by the piano to sing "I Gotta
     Be Me" while others begin rearranging your ornaments. 

Level III: 

     Your guests are arguing wildly among themselves, those that haven't
     passed out from the upside-down margaritas. One person is singing
     "I Can't Get No Satisfaction", which can barely be heard over the
     sound of breaking ornaments. A small group of guests begin placing
     hors d'oerves in the piano to see what happens when the little
     hammers strike. 

Level IV: 

     Your guests, hors d'oerves smeared over their naked bodies, are
     performing a ritualistic dance around the burning Christmas tree.
     The piano is missing. 

In general, you want to keep your party around Level III, unless you rent
your home, have insurance, and are carrying firearms. The quickest way to
get to Level III is egg-nog.
