Friday the 13th party

Scattered about the house will be 13 superstition cards with associated props.  At some point in the evening,  guests will take a quiz. So glad that there will be drinking!  I'll correct them (always the educator) and award a prize to the winner.  Also, I'll ask guests to share their own superstitions - fun and very revealing.  
Buzz:  always be on the lookout for future party decor.  For example, a four leaf clover for 3/17 was purchased knowing it would be used on 5/13.
