Theater Superstition - Graveyard Gift

Superstition: It's considered good luck traditionally to give the director and/or the leading lady, after closing night, a bouquet of flowers stolen from a graveyard (never give flowers before a performance - They are yet to earn them so it's bad luck!)

Graveyard flowers are given on closing night to symbolize the death of the show, and that it can now be put to rest. The rational origin is that theater was, as most people who have worked in the industry will tell you, never a greatly profitable profession and despite being macabre, graves were a great source of free flowers.
