THEATRICAL BAD LUCK #2
Never say "Macbeth" in a theater, sinc ethe play is associated with many tragedies and mishaps; instead call it the Scottish play. If you do happen to utter "Macbeth" in a theater, there are several ways to counteract the curse: Turn around three times; spit over your left shoulder; say the rudest word you can imagine (yes, that one); or speak a line from A Midsummer Night's Dream.
Using a mirror on stage is considered taboo--possibly due to the technical difficulty of lightin mirrors, but also because of the age-old belief that mirrors can open one's soul to the devil.
Some theater hands believe in leaving a ghost light lit when the stage is not in use. It is said that such lights keep alive the spirit of theaters.
F. Scott Fitzgerald (1896-1940)
